The week between Christmas and New Years is usually a time when we get to play with some new technology since a lot of people are out and many meetings are postponed. but this year we played with some *old* technology! we tried hooking up a 3.5" floppy drive to a microcontroller to see if we can read data from it. we learned a lot about floppy interfacing and also made a library that will connect with greaseweazle software to dump disk images using low cost hardware like the rp2040 pico The Great Search - Floppy Disk Drive Power Connectors! https://www.digikey.com/short/f0vp4zzh OK so one challenge we've disk-covered (ha) doing floppy interfacing is that you need to really power them right. The power connector is a keyed 2.5mm pitch right angle PCB mount part https://en.wikipedia.org/wiki/Berg_connector let's find a connector on Digi-Key we can use in our design! #deskofladyada #thegreatsearch #adafruit @Digi-Key Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

time to wrap up today's hacking! we had a goal of finishing today with a raspberry pi pico board being able to read out flux off a floppy disk, and here we are: this is a ultra-low cost dev board, only $4 and 15K in stock at Digi-Key https://www.digikey.com/short/f2d841fn - a little soldering is required to attach header but the wiring is straight forward: start at GP2 and connect all the pins thru to GP14 in a row, skipping over the ground pads (dont forget to connect one of the grounds of course) we just tested dumping our 1.44 HD diskette just fine. in the next week we'll try to add flux writing support (we've only done reading so far), trying out HFS DD (so we can image @anildash's prince floppy), completing a PR to greaseweazle and maybe trying out the disk ii connection. a great way to kick off 2022, happy new year! #adafruit #raspberrypi #rp2040 Cross-platform interfacing hardware for floppy disks, part 8 - PINK TIME! https://youtu.be/OpAN5FSmPBw https://blog.adafruit.com/2022/01/01/cross-platform-interfacing-hardware-for-floppy-disks-part-8-pink-time/ YAY! floppy disk interfacing part 7, a floppy flux milestone! https://blog.adafruit.com/2022/01/01/yay-floppy-disk-interfacing-part6-a-floppy-flux-milestone/ https://youtu.be/IrSwMuFk-2c reading floppy disk data part 6, MFM sector decoding https://youtu.be/mE-77nEXbGc https://blog.adafruit.com/2022/01/01/reading-floppy-disk-data-part-6-mfm-sector-decoding/ reading raw floppy disk data part 5, at night the greaseweazles come https://blog.adafruit.com/2022/01/01/reading-raw-floppy-disk-data-part-5-at-night-the-greaseweazles-come/ https://youtu.be/e6v7Q4h5JBM interfacing with floppy disks at low level, part 4 https://blog.adafruit.com/2021/12/30/interfacing-with-floppy-disks-at-low-level-part-4/ https://youtu.be/a-zH9wdNwnE Reading floppy disk data, part 3! itsa pulse party https://blog.adafruit.com/2021/12/29/reading-floppy-disk-data-part-3-itsa-pulse-party/ https://youtu.be/kynoLRQpDnU Adding floppy disk support to CircuitPython, step 2 https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-2/ https://youtu.be/frnJ7pWr5Zg Adding floppy disk support to CircuitPython, step 1… https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-1/ https://youtu.be/ceyM6vYpT74 Adafruit Floppy is a project to make a flexible, full-stack, open source hardware/software device for reading, archiving, accessing and duplicating floppy disk media.

now that we have successful flux reads, its time to get flexible! we've swapped our SAMD51 feather board out for an RP2040 feather. not only is this feather a lovely pink shade, but it comes with a totally different chipset. oh no, do we need to start over completely with a new toolchain, timer configuration and dma library? nope! our code is hardware agnostic enough that with pin name tweaks and a couple ifdefs, we can use it just fine with greaseweazle again. so now our library has 2 chips it can use, very handy when there's a silicon shortage going round. next up, could we use the $4 raspberry pi pico board??? stay tuned :) YAY! floppy disk interfacing part 7, a floppy flux milestone! https://blog.adafruit.com/2022/01/01/yay-floppy-disk-interfacing-part6-a-floppy-flux-milestone/ https://youtu.be/IrSwMuFk-2c reading floppy disk data part 6, MFM sector decoding https://youtu.be/mE-77nEXbGc https://blog.adafruit.com/2022/01/01/reading-floppy-disk-data-part-6-mfm-sector-decoding/ reading raw floppy disk data part 5, at night the greaseweazles come https://blog.adafruit.com/2022/01/01/reading-raw-floppy-disk-data-part-5-at-night-the-greaseweazles-come/ https://youtu.be/e6v7Q4h5JBM interfacing with floppy disks at low level, part 4 https://blog.adafruit.com/2021/12/30/interfacing-with-floppy-disks-at-low-level-part-4/ https://youtu.be/a-zH9wdNwnE Reading floppy disk data, part 3! itsa pulse party https://blog.adafruit.com/2021/12/29/reading-floppy-disk-data-part-3-itsa-pulse-party/ https://youtu.be/kynoLRQpDnU Adding floppy disk support to CircuitPython, step 2 https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-2/ https://youtu.be/frnJ7pWr5Zg Adding floppy disk support to CircuitPython, step 1… https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-1/ https://youtu.be/ceyM6vYpT74 Adafruit Floppy is a project to make a flexible, full-stack, open source hardware/software device for reading, archiving, accessing and duplicating floppy disk media.

whew! so, turns out it was an underspec'ed power supply. so now we know, 500mA is not enough for a floppy drive you really need 1A. but with that out of the way, we were able to cleanly read all 160 tracks of flux from a floppy disk! this particular disk is one that our friend hid in that place that one time, and we've been waiting to be able to see what's on it... will we be able to extract the sectors and discover what secrets lie within??!?

we fixed some track seeking code errors we had, and now we're able to start getting data from greaseweazle. since the diskette we've got is an ibm pc 1.44MB format we can use the built in ibm pc MFM format decoding module. the good news is that its able to decode *some* tracks...but its not able to decode all of them, like it'll read 10 good sectors in a row, then just cant find any sectors at all - which is a little suspicious. makes us wonder if we got the flux transfer and index pulse encoding right, or if its a formatting thing, because the diskette is readable on a computer with a usb drive connected. reading raw floppy disk data part 5, at night the greaseweazles come https://blog.adafruit.com/2022/01/01/reading-raw-floppy-disk-data-part-5-at-night-the-greaseweazles-come/ https://youtu.be/e6v7Q4h5JBM interfacing with floppy disks at low level, part 4 https://blog.adafruit.com/2021/12/30/interfacing-with-floppy-disks-at-low-level-part-4/ https://youtu.be/a-zH9wdNwnE Reading floppy disk data, part 3! itsa pulse party https://blog.adafruit.com/2021/12/29/reading-floppy-disk-data-part-3-itsa-pulse-party/ https://youtu.be/kynoLRQpDnU Adding floppy disk support to CircuitPython, step 2 https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-2/ https://youtu.be/frnJ7pWr5Zg Adding floppy disk support to CircuitPython, step 1… https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-1/ https://youtu.be/ceyM6vYpT74 Adafruit Floppy is a project to make a flexible, full-stack, open source hardware/software device for reading, archiving, accessing and duplicating floppy disk media.

HAPPY NEW YEAR EVERYONE! we're ticking down the new year safe and sound here at home together, with a big mug of cocoa, and a lot of floppy hackin'. tonight we started adding 'greaseweazle' support to our arduino floppy library. this will let us use any fast-enough arduino hardware with a fabulous open source flux parsing tool that is written in python. basically, we send the flux pattern for each track over usb serial for it to be parsed or saved on a computer. we have been adding each command throughout the day: enabling the motor, running a bandwidth check, setting drive parameters, etc. we are halfway through the track reading code - we got the read data arriving safely at the computer, but it seems that there is a way to 'encode' the index pulse into the flux stream and we have to figure out what polarity and data format its expecting. still, feeling really close! hopefully will be able to dump our first disk image this weekend :) code is here while its being worked on https://github.com/adafruit/Adafruit_Floppy/blob/main/examples/greaseweazle/greaseweazle.ino interfacing with floppy disks at low level, part 4 https://blog.adafruit.com/2021/12/30/interfacing-with-floppy-disks-at-low-level-part-4/ https://youtu.be/a-zH9wdNwnE Reading floppy disk data, part 3! itsa pulse party https://blog.adafruit.com/2021/12/29/reading-floppy-disk-data-part-3-itsa-pulse-party/ https://youtu.be/kynoLRQpDnU Adding floppy disk support to CircuitPython, step 2 https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-2/ https://youtu.be/frnJ7pWr5Zg Adding floppy disk support to CircuitPython, step 1… https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-1/ https://youtu.be/ceyM6vYpT74 #floppy #adafruit #retro Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

from the (kitchen table) desk of ladyada & pt ... new year's hackin' 2021

we're going to back up a little in this part - we have MFM and index pulse data coming out of our chonky panasonic 3.5" floppy drive and capturing that well. but now we're a little curious of how folks are going to use this if floppy drives arent available. we had to pay a pretty penny for this drive, second hand, and that makes it tougher for more folks to get drives and use them to read floppies. we did have a USB floppy drive (originally ordered to read out our mavica camera images) and now we're curious how it works so we opened it up! inside is a samsung SFD-321S which is we'll take as the "S"MT version of the SFD-321B datasheet we read earlier. (we couldn't find a datasheet for this 'S version tho). Instead of the 34-pin IDC there's a 26-pin 1mm FPC connected to a cheapy adapter board with a single sanded-off 28-tssop chip. the chip is handling the Mass Storage - FDD conversion all on is own. but it's too smart for us! we don't want MSD, we want those delicious flux transitions. thankfully this nice person posted up the pinout for us https://jestineyong.com/examining-and-testing-a-small-universal-fdc-to-usb-adapter/ and when we probed the index and data lines while accessing the disk, we found nice MFM traces coming out. next up we're going to design a quicky adapter from 26-pin FPC to 34-pin IDC pin header & breadboard. (we did find some converter PCBs but all going the opposite way!) part 3: https://youtu.be/kynoLRQpDnU part 2: https://youtu.be/frnJ7pWr5Zg part 1: https://youtu.be/ceyM6vYpT74 #floppy #disk #retro ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

OK so part 1 we got our wiring worked out and found an index pulse. Part 2 is we started getting MFM data coming out. Now we're capturing pulses with gpio bitbanging, and storing all the pulse widths in a large memory array. each track has a 500Khz signal, and outputs data every 5 Hz, so we have a max of 100K samples worst case. since we're using a cortex arm with 192K~256K of RAM (the RP2040 has 264K!), its no biggie to store all the pulses in an array. here we are reading track 1 and binning the pulses: we're seeing three pulse width bins stand out, about 40 count, 62 count and 85 count. but there's also a couple ultra short pulses (25 count) and an ultra long pulse (~200 count). each count is about 48ns-ish so that translates to 2us, 3us and 4us bins, with a few 1us and one or two 10us+. not exactly sure whats up with those outliers. do we ignore them? are they start-of-data markers? We also noticed that track 0 has way more unusually long or unbinned pulses, like almost 100 different values. its a little mysterious, we'll have to investigate if there's something special about track 0!

OK now that we've gotten the motor up and running, and the drive selected in step 1 - we know our wiring is correct. step 2 is getting data out! unlike almost all protocols we're used to, there's no clock pin on floppy data. it comes out in MFM format (at least, this floppy disk format does) which means we get a series of ~500kHz open-drain pulses with short negative widths, and varying positive widths that indicate flux transitions. now the *proper* thing to do here is use a PLL to sync up with the pulses since the motor speed can vary a few %, then convert the pulse widths to bits of data. but we're gonna do it dirty to start, and just busy-poll the pin using a fast register gpio read and collect pulse widths, then maybe decode and bitpack them on the fly. not sure if this is workable yet, but it looks OK so far: just started collecting the data pulses and they seem to be binnable. part 1 is here: https://youtu.be/ceyM6vYpT74 #floppy #python #arduino Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

If there's one thing we believe in strongly here at Adafruit its that if you have an embedded interpreted language running on your microcontroller, it's super important that you can access floppy drives from it. Sure, sure, you could use a micro SD card, but microSD cards can get lost easily compared to a chonky 3.5". So we're starting to look at how to get a floppy drive up and running. The good news is you can use 5V power and it seems to be ok with 3V logic levels. We've got the idc cabling wired up right we think, because we can now turn on the motor and see index pulses coming out at around 5Hz. This Samsung SFD-321B datasheet has been really helpful in interfacing, and so far our code is in Arduino since we're comfy with that for hardware noodling. We'll publish it as a cross-platform-usable open source hardware so folks can keep on spinnin'. https://cdn.datasheetspdf.com/pdf-down/S/F/D/SFD-321B-Samsung.pdf #floppy #python #arduino Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Ooh its the end of the year, a very liminal time as it were! We are keeping warm and well-fed while wrapping up some projects. We got our Scorpio PCBs in, but we're still waiting on our 8-bit level shifter chips before putting em together. We also are working again on our Feather M4 Adalogger board. While doing so we started working on some Learn guide templates for Arduino, particularly since we're doing more low-power or 'unusual' configurations for our hardware and it can be a little odd to get onboard hardware working. The Learn guide templates are kinda interesting so we thought we'd show how they work!

This week's EYE ON NPI is so flexible, it's thinking of joining the Rockettes (https://www.rockettes.com/christmas/)! It's TDK's BCS Series Low Illumination Film Solar Cells that are designed for direct integration of products, particularly wearables or credit card size and thickness electronic components. This amorphous panel comes with 6 cells, each about 0.4V open-circuit, for a total of about 2.6V output and 30mA. The nifty part about this panel is just how incredibly thin it is - only 0.2mm which means it can be bonded onto almost any surface or device. And unlike most panels that are made of monocrystalline cells, it is ultra flexible and will not crack or break. TDK's BCS series are thin, lightweight, and flexible solar cells offering high power generation efficiency under fluorescent and LED light sources. The cells are made of amorphous silicon film substrate, and designs can be customized according to various shapes and applications. Because BCS series solar cells offer output stability in low and dim light, they are suitable for use in products used indoors. Additional benefits of solar cells include cost reduction in electrical wiring and battery replacement. When used in combination with a primary battery, solar cells can extend battery life and usage time of rechargeable devices. BCS series solar cells can be used in applications such as watches, wearables, beacons, wireless sensor nodes and other IoT power supply applications, smart cards and locks, and more. Compared to many other ultra-low power source harvesting techniques (https://en.wikipedia.org/wiki/Energy_harvesting) like vibration/piezoelectric or heat, solar is very efficient, very small and very easy to use. Amorphous cells are a great option for folks who want to have indoor-powered electronics without hassle. Simply connect the two terminals to you circuitry plus and minus: when there's ambient light, you'll get voltage output. These panels may look familiar if you've ever had a solar-powered calculator (https://en.wikipedia.org/wiki/Solar-powered_calculator) - often times you'd have to hold these up to a lamp to get them 'kick-started'. Those pocket calculators with LCDs are a great example of ultra-low current draw electronics that could run off of a tiny cell, we're talking under a milliamp here. That's something to keep in mind when integrating panels, they produce about 1/10th of the power folks think they do! The biggest challenge that folks have with implementing solar panels is that they don't really act like a true voltage source or current source: they're somewhere in the middle, like a negative diode. With solar panels, the voltage and current vary constantly depending on sunlight available. They are unstable! That instability confuses electronics battery chargers, which causes them to do one of two things: rapidly turn on and off as they try to draw more current from the panel than possible and/or draw much less current than they can, to keep the voltage from collapsing. So you've got a few choices for implementing this panel: 1) have electronics that is OK with a widely varying input voltage: about 2V to 5V max, and will brownout safely when light disappears all of a sudden. Then, make sure it uses less than a few mA of current so that it doesn't collapse the IV curve by drawing too much power 2) use a super capacitor or rechargeable battery of some sort, that is trickle charged by the panel. once the voltage on the cap gets to a certain amount, the circuitry can use that to perform whatever calculators or data transfer required. 3) use a smart energy-harvesting chip like the LTC3588 (https://www.digikey.com/en/products/detail/analog-devices-inc/LTC3588EMSE-1-TRPBF/2216345) to manage the load on the panel and either charge a battery or directly power electronics with a cleaner supply than directly powered from the solar cell. Sometimes these chips can even operate as a MPPT charger (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) to get the very max power possible. If you're interested in adding a super-flexible and ultra-thin green power supply to your next design, check out the BCS4430B6 (https://www.digikey.com/short/vwm3z35j) and friends.

Ladyada's desk is jam packed with goodies :) first up, we're trying to always order the tester PCBs when we get our panels in, so we don't have to mill out a prototype on the bantam unless something goes amiss. this is a 'drop n beep' tester - where it repeatedly attempts to test and then beeps/blinks on success. the production team loves these kinds of testers. then, we got some 'pantone chips' made of PCB material with copper underneath, from our board house, to match the PCBway pink. this is so we have two sources of PCBs - we've been seeing lockdowns take out some of our suppliers lately! this is Pantone 204 C (hex #E782A9). nice color right? don't forget, you can STILL get a free pink Feather RP2040 when you order $99 or more from adafruit.com - https://www.adafruit.com/product/5299 we will run out in a few days so don't wait too long! #adafruit #pink #pantone Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Lots of people don't like to admit when they make a mistake - but we love to share our 'happy little accidents' so folks can learn from us! We had ordered PCBs for the ESP32-S2 TFT Feather and realized right before going into production that while we were depowering the I2C power (to turn off external sensors while going into deep sleep, for example) we still have the I2C pullups enabled...this caused higher current due to the back-powering leak. Woops! But hey, we either win or learn something. So here's a quick re-spin we did to verify we got it right this time. The PM2.5 is a massive I2C device, and here we are going into low power and deep sleep for one second each, to verify that we are hitting that 80uA in deep sleep for sure. Now we're ready to book the PCB! #adafruit #esp32 #esp32s2 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

For the SCORPIO Feather, we need to buffer 8 outputs for NeoPixels from a 3V signal to a 5V signal. The '245 is the transceiver we have traditionally used - but we need a very smol chip, that can also handle if the logic level is 3V and the power supply maybe gets towards 5.5V, thus getting dangerously close to 1/2 VCC. We'll show why the T is important!

OK so to get the QT Py manufactured we need a tester. In this case we're not going with a teensy or arduino because the fastest way to program an esp32-s2 (we've found) is with the compressing stub loader that esptool.py uses. also, we're going to be doing a wifi signal test where we scan on the Raspi for the ESP's access point - this is a simple but effective way to make sure the antenna is on right. the tester python code runs on the pi, with a pitft for colorful text output and buttons to start test. another great example of using your own tools to make tools that are used to make other tools! #adafruit #esp32s2 #qtpy Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week's EYE ON NPI is *PIRfect* for adding human-motion detection to your product or project - it's Panasonic's new PaPIR sensor line-up (https://www.digikey.com/en/product-highlight/p/panasonic-electric-works/ekmb-ekmc-series-flat-square-lens-type-pir-motion-sensors), featuring ultra-low power current consumption, a jaunty square shape, and multiple color options so your sensors will be detecting in style. PIR sensors are great for detection motion of humans and other large & warm things. They are particularly excellent for making your designs use less power / be more 'green' because you can detect when a person walks into the room or in front of your control panel: so monitors or lights can be disabled or dimmed when there's no people around. Or your thermostat will know that it doesn't need to turn on the AC or heat since nobody is at home. And it does this all without video cameras, face detection or cloud computing (we're only being slightly sarcastic here!) The PIR sensor element itself has two or more slots in it, each slot is made of a special material that is sensitive to IR. The two slots can 'see' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a negative differential change. These change pulses are what is detected. The Panasonic PaPIR modules (https://www.digikey.com/en/product-highlight/p/panasonic-electric-works/ekmb-ekmc-series-flat-square-lens-type-pir-motion-sensors) take a full circuit board's worth of PIR support components and tuck them all into the metal can that fits beneath the plastic lens of the sensor. Since it is fully integrated, you only need to solder in 3 wires: power, ground and output for instant detection up to 5 meters away. There are other PIR sensors available, but they tend to be kind of large and are hard to integrate into a design directly. (https://www.adafruit.com/product/189) - they're best for maker projects not necessarily products. The EKMB/EKMC designs from Panasonic brings a very compact and ultra-low power solution for when you want a small 5 meter-range PIR sensor that can be soldered directly to a board. And the power draw is super low - about 1~20uA, so it can be used for battery powered products. Since it's so low power, you could connect the output pin directly to an enable pin for a power supply or to a transistor for turning on power to lights or a buzzer. Note that the ambient current draw will affect the stability warm-up time and the sensitivity, so you'll probably want to try different ones in-situ to see the minimal current draw you can get away with. *PIRhaps* you're interested in picking some up? Well, today is your day cause Digi-Key has all the different sizes, colors and sensitivity options available for purchase right now in stock! Visit the Panasonic EKMB/EKMC Series Flat Square Lens Type PIR Motion Sensors feature page (https://www.digikey.com/en/product-highlight/p/panasonic-electric-works/ekmb-ekmc-series-flat-square-lens-type-pir-motion-sensors) to place your order today and you will be able to add ultra-low-power sensing by tomorrow afternoon.
