It's getting hot here in New York City, we could use a little help cooling off, and this week's EYE ON NPI an ultra-cool blast of Nordic engineering - the nPM1100! It's the first power management IC from our favorite low-power-wireless company, Nordic Semiconductor. We've featured them on EYE ON NPI before - the Nordic Power Profiler Kit II (https://blog.adafruit.com/2020/12/03/eye-on-npi-nordic-power-profiler-kit-ii-eyeonnpi-digikey-nordictweets-digikey-adafruit/) and the nRF53840 microcontroller (https://blog.adafruit.com/2020/03/20/eye-on-npi-nordic-semiconductors-nrf5340-bluetooth-eyeonnpi-maximintegrated-digikey/) - and we've been using Nordic BLE chips for quite a while in our Bluefruit line of boards (https://www.digikey.com/en/products/filter/rf-evaluation-and-development-kits-boards/859?s=N4IgTCBcDaIEYBsCuBTAZgJyQSwC4gF0BfIA) For us Nordic is synonymous with Wireless and Low Power. That's their bag, and if you need something that's BLE and runs on a small battery for a long time, it's probably the product like you're going to use. Even Apple, who have gotten serious into designing their own silicon used the Nordic nRF52 series for the AirTag (https://www.ifixit.com/News/50145/airtag-teardown-part-one-yeah-this-tracks) When you make products that are designed and marketed to be used for low power wireless - like motion trackers, beacons/tags, fitness watches/bracelets, environmental monitor, etc. the power management system becomes less of a independently-run subsection of the electronics design. As we've seen in other EYE ON NPI's, there may be times when you drop the voltage down or raise it up to change quiescent current and RF transmission. A lot of Cortex chips we've seen lately have integrated buck converters that can be enabled/disabled on demand - they have higher quiescent current than LDOs, but may have lower overall run current during high draw. Buck converters also require an inductor, of course, and will have higher noise. Getting long life from battery is very hard, much harder than people think, and requires good firmware, hardware and integration design. Given the creating of the PPK2, it seems obvious to us that a lot of Nordic's time has been spent trying to get their their customers going with the battery performance they need without doing their design for them. A lot of time folks don't understand the way quiescent currents add up to drain batteries. To solve this for Nordic's customers, they've pulled the PMIC's that were historically integrated into the nRF52840 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-QIAA-R7/11200025), nRF5340 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF5340-QKAA-R/13559661) and nRF9160 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF9160-SICA-R/12339212) and super-powered it into the nPM1100 (https://www.digikey.com/short/38n9f9dv) - an all-in-one battery charger, regulator and buck converter. Ultra-small form factor PMIC 2.075 x 2.075 mm WLCSP package 400 mA battery charger Termination voltage: JEITA compliant 4.1 V or 4.2 V selectable Charge current: 20 mA to 400 mA Highly efficient Buck regulator Output voltage: 1.8, 2.1, 2.7 or 3.0 V Current limit: 150 mA output USB compatible input regulator Overvoltage protection Ship mode disables power output Quiescent currents: 800 nA typical, 460 nA in ship mode Drivers for charge and error LEDs -40°C to 85°C operating temperature Things we like - this chip is fully standalone and strapped with resistors or pins so you don't have to configure it over I2C or 1-Wire or anything and two direct LED outputs for instant visible feedback with a bi-color LED. Works with USB but has input protection for higher voltages in case something gets mis-plugged. Three-in-one integration design means you can pick and choose the pieces you want. It's clearly designed for boards that use sporadic power, and has a 'ship mode' to reduce power draw while its in storage/shipment to the customer - many of these devices don't have a true Off button/switch, so before the first use they'll want to be disabled/enabled with soft-switch buttons to wake up. In Nordic's case studies, they were able to up the run time of a wearable health-monitor bracelet by taking advantage of the buck converter to reduce run-time quiescent current. While designed for Nordic wireless chipsets, this PMIC would be well suited to wearable/low-power designs and you know that Nordic takes low power very seriously so this chip will hit the ground running with a tiny chip that does it all. Bare nPM1100 chips (https://www.digikey.com/short/5dwz72j7), as well as the eval boards (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NPM1100-EK/14310011?s=N4IgTCBcDaIHYAcC2BGFAGdIC6BfIA) are in stock right now for immediate shipment!

Adafruit seesaw is a near-universal converter framework which allows you to add add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C GPIO expanders, ADCs, PWM drivers, etc, seesaw can be configured to give a wide range of capabilities. And now we've got our seesaw peripheral library ported to Arduino IDE & humming along nicely - here's a demo where we have an I2C controller read a trim potentiometer over I2C, then turn that into NeoPixel brightness settings and pipe out a rainbow demo to a NeoPixel strip over I2C. #adafruit #seesaw #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/ -----------------------------------------

Catching up to a project we started last month - we need to redesign some of our boards due to the chip shortage. We decided to move from the SAMD09 to the ATtiny816 (https://blog.adafruit.com/2021/05/18/the-great-search-a-very-inexpensive-seesaw-8-bit-microcontroller-thegreatsearch-digikey-digikey-adafruit-microchipmakes/) because it seems available/low cost and capable enough. Once you've spec'd the chip, it's nice to get an eval board or two. This will get us going quickly! I'll share some tip for what I look for in an eval board, as well as how to find an eval board even if one doesn't exist for your chip (!) —————————————- Catch live airings of The Great Search in the Desk of Ladyada broadcasts – playlist https://youtu.be/46zAO_3-ozY —————————————– 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/

Build a smart DIY fume extractor with an Adafruit FunHouse and CircuitPython. Use a PWM fan and the EMC2101 controller to change the speed based on readings from an SPG30 air quality sensor. Learn Guide https://learn.adafruit.com/funhouse-fume-extractor/ Project video by Liz https://youtu.be/3rwHkWDBnlA Use CircuitPython libraries and ESP32-S2 to connect to WiFi and log sensor data to a feed and display it on a dashboard with Adafruit IO. Use the FunHouse’s built-in TFT to display bitmap graphics with fan speed and air quality. Use the built-in buttons to select options like choosing to log data. CircuitPython makes it easy to customize features, experiment with other hardware and quickly iterate. The electronics are housed in a 3D printed enclosure that snap fits together. Use a carbon activated filter to adsorb smoke from solder fumes. The fan controller and air quality sensor are connect with STEMMA QT cables for a plug-and-play circuit. A mini fan mounted in front of the air quality sensor directs fumes for sampling and measuring. The ports on the FunHouse make it easy to power 5V peripheral.

Seesaw is an open source microcontroller friend for other chips. It provides a variety of capabilities such as UART, ADC, DAC, extra GPIO, etc. to chips that don't have them. We've used the SAMD09 for seesaw for years, and it's been great. But now we can't find any SAMD09 on the market for a year or two - so it's time to redesign!

This week's EYE ON NPI is all in on keyboard hacking, just like us! The Mill-Max 3305 series open bottom, low-profile, solder mount receptacles are specifically designed to make mechanical key switches hot-swappable. The 3305 series is designed to be soldered into a 0.060” (1.50 mm) minimum mounting hole with an ultra-thin retention shoulder so plugged-in components sit nearly flush to the board surface. The open bottom design is meant to accommodate varying lead lengths, making this a very versatile receptacle. These sockets are popular in the keyboard building and modification community for allowing folks to have PCBs that allow socketing or direct-soldering of switches without any height changes or PCB layout changes. Compared to previous sockets manufactured by Mill-Max, the 3305's are lower profile and have gold plating for long-life reliable contacts. Cherry MX switches (https://www.digikey.com/en/products/detail/cherry-americas-llc/MX1A-E1NW/20180) have a standardized pinout, with a large center hole - two optional side-stability holes and two normally-open contacts. Cherry offers a wide range of switches with the same pinout/physical shape but with different mechanical attributes - some are smooth/linear, some are loud and clicky. Of course, many people like to customize what the switches are on a keyboard. Now, hopefully your keyboard manufacturer comes with different options for keys. but maybe you're doing a build or its an older design you want to update. You can carefully de-solder switches to replace them, but it's much better to socket them like we do with chips. (https://www.adafruit.com/product/2203) Sockets do exist for MX switches, (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4958/13997772), at this time both Gateron and Kailh make em. The good news is they work quite well - but they do require a new PCB layout for the SMT pads. All good for folks making new designs. But, sometimes you don't have the ability to change the design - or for some constraint reason you don't want to use these sockets. That's where the Mill-Max 3305's come in! (https://www.digikey.com/en/product-highlight/m/millmax/3305-series-open-bottom-receptacles) These ultra-slim ferrules can be soldered into existing plated through holes that are made in a PCB design. After soldering them in, two per switch, they accept the rectangularish contacts on MX and compatible switches. Best of all, they come in pick-and-place tape so you can integrate these into your manufacturing process or solder by hand. Now, you might be thinking "this seems really specialized to a specific purpose, why bring this up on EYE ON NPI?" Aha, because while these are designed for use with MX switches, these could be used to socket all kinds of through hole parts without changing PCB layout or height. For specialized parts, sensors or tubes or specialized displays, there may not be a plug-and-play ready to go socket available. But you still don't want to solder it right into your PCB? Check the lead sizes...you may be able to use these inexpensive sockets! Best of all, since they're open-bottom you can go with any length chip lead. Various lengths of Mill-Max 3305 sockets are in stock right now at Digi-Key for immediate shipment. (https://www.digikey.com/short/45bfzdj7) Order today and you can start socketing securely by tomorrow morning!

For the KB2040 board we're working on, we want to add a PTC fuse. These fuses auto-'heal' after they cool down and they're pick and place friendly, so they're easy to use. We're going to add one to this board so it has similar behavior as the Pro Micro it is pin-compatible with. PTC fuses are available in a few different voltages, current ratings and sizes - let's find the one we need for this tight-fit PCB!

our custom keycaps arrived - they're translucent plastic with a thin black opaque layer that is etched away in a custom design. so of course we got one with an adafruit logo on it, looks pretty sweet! as shown here on our macropad we've got it so launches adafruit.com on a computer when pressed but of course it can go on any keyboard with cherry mx compatible switches. #adafruit #keyboard #keeb 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/ -----------------------------------------

We put together our hopefully-final prototypes for the Macropad we're working on at the office. Now we're home and it's time to bring up the design. We like to do our bring-ups in Arduino, so we're using the Philhower Arduino core to make a definition and verify all the hardware works. The new part here is the OLED, which uses a new chipset, but similar enough to other OLEDs we wrote a driver pretty fast. This test program lights up all the switch neopixels, tracks the rotary encoder direction and pushbutton, and scans I2C connected to the Stemma QT port. So far so good! #adafruit #keyboard #macropad 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/ -----------------------------------------

We're back to working day-shifts in the office, which means access to our mega-oven for prototypes. We loved ya, lil reflow plate, but for bigger protos like this an oven really does a great job. We're pasting the components by with a syringe, then hand placing the parts for two protos. After a trip through the oven, we do a little hand-cleanup of bridged pads and then it's time to bring up the board!

This week on the Desk of Ladyada we're doing the bringup of our hopefully-final revision of the RP2040 macropad we're working on. Arduino is working solidly, and CircuitPython is getting there. We have to get the OLED driver bugs ironed out but the hardware seems solid! Next up, we've acquired a TI calculator running a fork of CircuitPython. Let's check it out and see what has been added. The Great Search - SMT PTC Fuses https://www.digikey.com/short/24zcmdwc For the KB2040 board we're working on, we want to add a PTC fuse.

Now that we have my hardware validated in Arduino, it's time to get it running in CircuitPython as well. We needed to write a little patch to the core to fix a row/col swap so that the SH1106 driver will work right https://github.com/adafruit/circuitpython/pull/4864 however, once we got that fixed, the display/buttons/encoder are working perfectly. Next up maybe we can get the onboard audio working so that the final PCBs can be ordered. #adafruit #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/ -----------------------------------------

We sure love our Cherry MX compatible switches, but let's be honest....they're kinda big. What if you want something svelte? The Kailh CHOC v1's are much shorter. Here are some samples we are testing out of clicky white and linear red Choc1's with two color options for keycaps and PCB sockets. Watch out - these are totally incompatible with MX-series sockets and caps! Still, so worth it for that low-low-profile. #adafruit #keyboard #keeb 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/ -----------------------------------------
