Most of our testers use pretty simple gpio toggling to verify everything's connected - but for our Radio Feathers https://lnkd.in/gsrgRF9C we want to also verify that the radio signal is connected through properly. so we use a separate radio to ping pong a message and check the RSSI. traditionally we did this with separate radio feathers but that got a little annoying to manage since they'd get lost or the battery would be dead just as we were about to get on with some testing. since our new fancy Tester Brains https://lnkd.in/eGCQmvnt got an upgrade from teensy to pico, we also revised to add an EYE-SPI connector which brings plenty of GPIO and SPI over. now we have the second RFM module connected to the tester itself so it's all-in-one. a lot easier to manage!

NeoPixel LEDs (a.k.a WS2812 / SK6812 family) are a super-easy way to add addressable RGB lighting with only one GPIO. they're ubiquitous on microcontrollers, but some chips or SBC's dont have neopixel support due to the precision timing required to send data. we often get folks asking how to get NeoPixels working on some OrangeBananaOnionRockchipAllWinner Pi type board, given we have our Blinka library that provides support for CircuitPython libraries. but if theres no neopixel_write implementation written for that platform, it just wont work. a quick solution is this seesaw-based NeoDriver board: send it the NeoPixel data you want to write over I2C and it will blit out the perfect pixel timing on the other side. we're using an attiny1616 so we have enough RAM to buffer a 512-pixel long strand. now, to be fair - its not super fast because we have to write each pixel over I2C https://learn.adafruit.com/adafruit-seesaw-atsamd09-breakout/neopixel, but with 1MHz clock and as long as you're not writing the whole strip at once, its not so bad! we add a 5V charge-pump so even on 3V boards, you'll get a clean 5V signal. pre-soldered terminal blocks and Stemma QT plugs make this a no-solder solution for adding NeoPixels easily to any device with I2C.

Kailh CHOC switches are low profile and are available in linear or clicky style https://www.adafruit.com/search?q=choc and they are very cool looking - but one thing they aren't is MX compatible! they have a totally different pinout so we need new breakout boards if we want to use them in a project. This is a simple 'port' of our NeoKey https://www.adafruit.com/product/4978 that has a CHOC socket https://www.adafruit.com/product/5118 and we're testing it here on a breadboard to make sure the button and NeoPixel works well before ordering final PCBs.

This week's EYE ON NPI is just in time for Earth Day - it's a new environmental sensor: the ScioSense ENS160 Air Quality Sensor (https://www.digikey.com/en/product-highlight/s/sciosense/ens160-air-quality-sensor) - a digital multi-gas sensor that offers optimum detection of volatile organic compounds (VOCs) and oxidizing gases. This is a 4-in-one sensor that improves on common MOX gas sensors that have become popular on the market, but is still super easy to use. This sensor is the successor to the popular CCS811 (https://www.digikey.com/en/products/detail/sciosense/CCS811B-JOPD500/6569311), which we used for many years and was one of the first embedded MOX sensors on the market. It was quite popular but only had one MOX plate, and has been improved with the introduction of the ENS160. Gas sensors are all essentially resistive sensors, where the exposed silicon has a metal oxide layer (MOX) that is susceptible to ambient gasses. There's a heater element that you need to turn on, then wait until the silicon chunk can react with the air. The resistance changes with the amount of organic compounds in the air and you can measure the resistive differences. (https://en.wikipedia.org/wiki/Electrochemical_gas_sensor) Traditional gas sensors came with 4 pins: two for the heater, and two for the resistor. You have to power the heater, then use a resistor divider or op-amp to read the resistance and back calculate. (https://learn.adafruit.com/gas-sensor-comparison/connect-the-sensor-boards) There's no built-in calibration available, you'll have to figure out what each resistance 'means' in human-friendly terms like AQI or ppm/ppb concentrations. This made a lot of gas sensors difficult to use, and also unreliable without constant upkeep. (https://www.google.com/search?q=alcohol+sensor+calibration) The new generation of MOX gas sensors follow in the footsteps of humidity sensors that were originally just capacitive sensors, but now are fully integrated with instant usable data. The CCS811 was one of the first to do this, a real pioneer. For these types of sensors, the MOX element is hidden inside, and the heater is automatically or digitally controlled. Baseline readings are used to provide home or office-grade calibration where we may care more about changes in readings rather than absolute readings. For example, an office's eCO2 reading has increased over the day from "good" to "poor" - that would indicate a need to turn on an HVAC fan or alert someone to open a window. The ENS160 has 4 different sensor elements, each one will have slightly different MOX doping, which means it will react to different classes of gasses. Which is something to remember: it's not like you can tell which TVOC you're sensing - the whole family of ethanol, methane, acetone, etc. are all going to activate the sensing bodies. Likewise - if you need precision CO2 measurements, nothing beats an NDIR sensor (https://en.wikipedia.org/wiki/Nondispersive_infrared_sensor). But those sensors are also pretty expensive - and don't do TVOC sensing. For basic usage, eCO2 will work just as well and at significant power and cost savings. Likewise, if you need specific TVOC sensing, those will cost a lot more but they are tuned. What we like about the sensor is that it's fully integrated: no firmware blobs or NDAs required which means we were able to get it ported to Python without difficulty.(https://github.com/adafruit/Adafruit_CircuitPython_ENS160/blob/main/examples/ens160_advancedtest.py) There's also an Arduino library published by ScioSense for integration in any C/C++ build. The library supports temperature and humidity compensation as well. If you think the ScioSense ENS160 Air Quality Sensor (https://www.digikey.com/short/mcv97mq2) is a breath of fresh air, then you're in luck because they're in stock right now at Digi-Key for immediate shipment! You can also pick up some of the Adafruit-made breakouts for the ENS160 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/5606/16750376) to get you started fast - our breakout includes regulators and level shifting, so you can drive it from 3 or 5V power and logic. Order today and you'll have them in your hands by tomorrow afternoon.

our first version of the pico dvi bell didn't quite work, but the second version has the right pinouts and is ready for testing. here we're trying it with CircuitPython *and* WiFi support: so we're able to connect over the internet with SSL to a site, get data, and then display it on a monitor. since the Pico W requires a lot of memory for the wireless connectivity we're using monochrome DVI output which means we have about 50K remaining after the framebuffer is allocated for the DVI display. CircuitPython supports 1, 2 or 8 bit color which you can configure based on your memory availability!

From our mailbag, a request from a viewer! "Hey, I recently had a terrible time on digikey finding a push-on push-off switch... I think because I was not understanding their "switch function" filter... Would love a video about it sometime!" A great question for a great search, let's take a look at a panel mount switch with Push-On Push-Off capability. There's a lot of tricky search elements to select, since Digi-Key stocks soooo many of these! See the chosen part at Digi-Key at https://www.digikey.com/short/pr9vr30f

the Intellikeys is a popular accessibility device with custom overlays, that is no longer supported. even though it has a USB plug it doesn't work like many USB devices: it doesn't enumerate as an HID keyboard, instead it downloads the firmware from the computer driver! that means it'll never work with many modern devices ike chromebooks or iPads...unless you've got a specialized device like the RP2040 Feather with two USB ports! we've loaded Thach's Intellikeys translator (https://github.com/adafruit/Adafruit_IntelliKeys) arduino sketch and it even does overlay detection so that when we switch out the paper it will enumerate as a different HID device. the code and hardware is all open source, so it can be maintained and improved for a very long time.

our line of RP2040 Feather 'bones' continues a-pace. this week its an e-ink capable feather. the rp2040 chipset is a great e-paper driver because its got tons of SRAM for buffering the image bitmaps all at once. almost all paper displays use the same 24-pin connection so its easy to swap out different displays. during the test procedure of this feather, we load a test code that flashes TEST OK and some lines onto a sacrificial 2.13 inch display. if it got that far it means all is well, and we can put this board into the shop.

This week's EYE ON NPI will stick by your side like a faithful hound- it's the BeagleBoard.org BeaglePlay® Single Board Computer (https://www.digikey.com/en/product-highlight/b/beagleboard/beagleplay). Single Board Computers (SBCs) are like tiny computers that are less powerful than desktops but much better at booting quickly and interfacing with hardware. They also tend to run Linux or BSD because it's easier to get those OS's ported to new chipsets than convincing Apple or Microsoft! This new generation of SBC from BeagleBoard builds on their prior success with the BeagleBoard (https://www.digikey.com/short/1cmb3dtf) and BeagleBone (https://www.digikey.com/short/c52dpz47) by adding a ton more interfaces and connectors so many projects can be built with no soldering. Here's a bullet list to get us started: AM6254 SoC processor 16 GB eMMC storage 2 GB DDR4 memory Supports expansion with OLDI, 4-lane CSI, and QWIIC connectors CSI for compatibility with the BeagleBone AI-654, Raspberry Pi Zero W, and compute modules Full-size HDMI connector Small size: 8 cm x 8 cm USB Type-C® with 5 V @ 3 A input connector mikroBUS connector RJ45 Ethernet connector for Gigabit Ethernet Wi-Fi 2.4 GHz and 5 GHz capabilities BLE and SubG MicroSD slot USB Type-A connector at 480 Mbit Grove connector The main processor is the TI Sitara AM6254 (https://www.digikey.com/short/507rmwr2) with quad-core 64-bit A53 and a Cortex M4 coprocessor. This chip is paired with 2 GB of DDR4 RAM and 16 GB of eMMC storage for a powerful AI-ready chipset that has tons of onboard graphics support such as 1080P HDMI and 4 lanes of OLDI/LVDS. This chip has 9x UARTS, 5x SPIs, 6x I2C's, 3x PWM modules, 3x quad encoders, and 3x CAN-FD, and of course some GPIO. Note there's no ADC or DAC - you'd use SPI to connect those externally. Note this board doesn't have a 2x20 header like a Raspberry Pi, or even the dual header strips from the BeagleBone - but in exchange it stuffs a ton of hardware support directly onto the PCB. For example, if you'd like to add a camera, there's an onboard 22-pin 0.5mm pitch CSI FPC connector that is compatible with the Pi Zero camera cables (https://www.adafruit.com/product/5211) - use that adapter to interface with any low cost Pi Camera modules or compatibles. For video output, a vertical full-sized HDMI port will connect to any monitor or display. In fact we plugged in our desktop monitor and powered the Play with a USB wall adapter, and it immediately came up with an X desktop display. Mouse and keyboard can be added via the USB 2.0 socket, a mini hub will allow multiple devices since there's only one type A port. The BeaglePlay does a great job of including everything you may want to expand your Raspberry Pi with. For example, there's a BQ32002 Real Time Clock (https://www.digikey.com/short/p0h10jbq) with a CR1220 coin cell holder right on board - normally that would have to be included as a separate module. A microSD card slot can be used for storing large amounts of data: unlike most SBCs, there's onboard 16GB eMMC so you don't have to juggle SD cards to install the OS. There's also a ton of expansion ports! For I2C, the onboard QWICC (https://www.sparkfun.com/qwiic) JST SH connector lets you use the hundreds of SparkFun sensors as well as any Adafruit Stemma QT (https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma) devices. For UART/PWM/ADC/I2C/GPIO you can use the onboard Grove connector. Finally, for networking either to the Internet or to a sensor network, there's Gigabit Ethernet, WiFi 2.4G and 5G, BLE and Sub-G networking. Yeah that's a lot! It's almost all provided by the onboard TI SimpleLink CC1352P7 (https://www.ti.com/product/CC1352P7) which boasts support for 6LoWPAN, Amazon Sidewalk, Bluetooth 5.2 Low Energy, IEEE 802.15.4, MIOTY, Proprietary 2.4 GHz, Thread, Wi-SUN NWP, Wireless M-Bus (T, S, C, N mode), Zigbee. Note LoRa is not in there, so if you need LoRa that would be added with a separate module. There's also an RJ-11 with Single-Pair Ethernet (https://blog.adafruit.com/2020/08/27/eye-on-npi-harting-single-pair-ethernet-eyeonnpi-digikey-ethernet-digikey-harting-adafruit/) which makes this a good fit to connect to industrial robotics or automation. All this hardware is available at a great price of under $100 at Digi-Key, we already picked one up and we're going to try and get Blinka working on it (https://github.com/adafruit/Adafruit_Blinka) so that all of our CircuitPython libraries will 'just run' in CPython. Especially given the ready-to-run Stemma QT / Qwiic port on the side, this is an excellent board for a powerful but solder-free configurable SBC. Digi-Key has tons of BeaglePlay's stock for immediate shipment, so order today (https://www.digikey.com/short/jpztmq3w) and you will be playing with your new BeaglePlay by tomorrow afternoon.

This week in our sample pile we have an I2C/SPI character LCD module we're checking out. Although historically 16x2 character displays use a parallel method of addressing - with 4 or 8 bit data input and a write latch - most folks don't want to waste so many pins on such a slow display. So, instead, many now come with I2C interfaces. That makes wiring or routing a lot easier! Digi-Key stocks a huuuuge range of character displays, let's check out what's available and some things to watch for with voltages, backlights, and polarizer types. See the chosen chip on Digi-Key at https://www.digikey.com/short/wd43mnwd

This weekend we took an itsy-bitsy-tiny-winy break from churning out new designs to try and dig our way out of the giant sample pile! we've got cool rotary encoders, some I2C LCDs, conductive fabrics, a miniature USB camera and more. Also, we'll snoop around tannewt's github repo to find a build of the DVI Feather for CircuitPython that now supports displayio to an HDMI monitor.

This week's EYE ON NPI is an EYE in the SKY, as we're featuring our first NPI from Skyworks: the Skyworks Si3404 and Si3406x Power over Ethernet [PoE] Powered Device Chips (https://www.digikey.com/en/product-highlight/s/silicon-laboratories/si3404-and-si3406x-power-over-ethernet-powered-device-chips). PoE is a standard, supported by many Ethernet hubs and switches (https://www.tp-link.com/us/solution/poe/) that allows a device connected to the hub to request +48V power over some of the Ethernet lines in Cat-5 cabling. Since many devices need Ethernet for speed and reliability - cameras, phone systems, printers, standalone monitors, and door entry systems, for example - you only need a single cable. These chips, originally from Silicon Labs and now made and sold by Skyworks, allow product designers to quickly add PoE support to their Ethernet products, saving space, complexity and wiring because a separate power supply is no longer needed.e First up, if you're wondering: "wow Skyworks, where have I seen that name before?" That's right! It was the California fabrication facility (https://en.wikipedia.org/wiki/Such_Great_Heights#Music_video) where The Postal Service's Such Great Heights video was shot (https://www.youtube.com/watch?v=0wrsZog8qXg). The original video even featured the Skyworks logos on the chips - now it's blurred out. But that's a great excuse for us to mention that there's a Postal Service/Death Cab 20th Anniversary Tour this fall and we are definitely getting tickets (https://giveuptransatlanticismtour.com/). But back to PoE chips! We watched a discussion video (https://www.youtube.com/watch?v=tEhbVpYFvk0) about the history of this chip line, we were struck by the observation that the reason PoE is so popular for office buildings is that it's very disruptive and expensive to get electricians to run power outlets everywhere. But running Ethernet can be done by the IT department because the voltages are so low that no special licensing or permitting is needed. Ethernet can be run behind drywall, around door frames, or under drop floors without worrying about electrocution or fire hazards. And you don't have to worry about DC plug adapters or voltage mismatches. The Si3404 can provide up to 13W (https://www.digikey.com/short/49dqqh9m), the Si3406 can do 25W (https://www.digikey.com/short/35jn99tc) but are otherwise very similar. Other than a few passives and full-wave bridge rectifiers, you only need the flyback inductor-transformer (https://www.digikey.com/en/products/filter/switching-converter-smps-transformers/168) - for isolated setups, it's a little more complicated. The Si3404 can also perform as a non-isolated buck converter for very small and low cost designs. The output voltage is set by a simple feedback resistor divider. Designs are compact, less than 1 square inch, for most use cases. Both the Skyworks Si3404 (https://www.digikey.com/short/49dqqh9m) and Si3406 (https://www.digikey.com/short/35jn99tc) are in stock right now at Digi-Key for immediate shipment. There are also eval boards (https://www.digikey.com/en/product-highlight/s/silicon-laboratories/si3404-and-si3406x-power-over-ethernet-powered-device-chips) that come with buck/flyback/isolated setups so you can test them as replacements for your current power supply to make sure which schematic you'll follow. Order them today for immediate delivery - through the Postal Service or whatever your favorite carrier may be - and you'll be making your IoT designs easy-to-power by tomorrow afternoon!

You can get 3D printed parts in clear resin using the 3D printing service from PCBWay. This video is not sponsored or affiliated with PCBway and the parts seen here were purchased on our own behalf. Learn Guide: https://learn.adafruit.com/clear-resin-3d-prints-with-pcbway/ These parts feature a crystal clear surface finish that’s reminiscent of the transparent gadgets of the 1990’s. They were 3D printed by PCBWay using UTR-8100 resin with the spray varnish option. This is a good option for makers who don't want to deal with the hassle and mess of 3D printing in resin.

This weekend we whipped up a quick FUSB302 (https://www.digikey.com/en/products/detail/onsemi/FUSB302MPX/5844455) breakout that will allow USB Type C sink power negotiation. Basically, we can plug into a USB hub or wall wart that can provide up to 20V and request that much voltage. This could be really handy for audio or robotics projects that need 9V, 12V, 15V or 20V without the fuss of finding a matching DC adapter. Now that we've got the chip, the datasheet lets us know that we need a separate, external 3.3V-ish regulator to supply power to the chip. Let's go looking for an LDO that can handle 5V-20V in, and provide 3.3V and at least 100mA, along the way we'll also check that we have voltage-rated components and also chat about LDO versus buck converters for this use case. See the chosen chip on Digi-Key at https://www.digikey.com/short/j3jtz4zm
