The Raspberry Pi Compute Module 4 is based on the Raspberry Pi 4 Model B, but in a smaller form factor – perfect for embedding into products or projects without the bulk of a classic Raspberry pi. You get all the computational power of Raspberry Pi 4 in a compact form factor for deeply embedded applications. The CM4 incorporates the same quad-core ARM Cortex-A72 processor, dual video output, gigabit Ethernet, UART, I2C, SPI, I2S and a few PWM for good measure.
Exposing every interface from Raspberry Pi Compute Module 4, the Compute Module 4 IO Board provides a development platform and reference base-board design for the most powerful Compute Module yet.
The Compute Module 4 IO Board is a development board for those who wish to make use of the Raspberry Pi in a more flexible form factor, intended for industrial applications. This replaces the previous Raspberry Pi Compute Module I/O Board V3).
PPE “Introductory” Pack – Protective Equipment Kit: This holiday season we think PPE will be the go-to gift, so we curated a couple of different packs with various levels of personal protective equipment with the DIY maker-community in mind. Whether it’s a tool for thermometer or fabric face masks, we’ve got you covered, literally
Our “Introductory” pack includes a disposable face shield, 50 pack of one-time-use blue masks, 3 x KN95 filtering face masks, one washable fabric mask, two rubber ear-savers for use with any mask, a no-touchy stick pointer, and a basic digital thermometer.
These Conductive Nylon Squares go great with our other interesting materials, such as copper tape, ITO glass or plastic, conductive inks, etc. We found that the metallic nylon fabric has some great improvements over plain copper tape.
Adafruit Metro ESP32-S2 PRODUCT ID: 4775 : What’s Metro shaped and has an ESP32-S2 WiFi module? What has a STEMMA QT connector for I2C devices, and a Lipoly charger circuit? What’s finishing up testing and nearly ready for fabrication? That’s right – its the new Adafruit Metro ESP32-S2! With native USB and a load of PSRAM this board is perfect for use with CircuitPython or Arduino, to add low-cost WiFi while keeping shield-compatibility
Adafruit 2.9″ Grayscale eInk / ePaper Display FeatherWing – 4 Level Grayscale: We’ve liked these displays for a long time, so wouldn’t a custom e-paper FeatherWing with buttons make a ton of sense? This ‘Wing is tested to work with all of our Feathers, from the ESP8266 to the M0. It has built in memory buffering so it can work with chips as small as the ’32u4 and ‘328. It does use a lot of pins: the 3 SPI pins, and up to 4 control pins to manage the SD card slot and SRAM. Plus 3 optional buttons are available for Feathers with available pins.
The FeatherWing sports a 2.9″ grayscale display with 296×128 pixels. Each pixel can be white, light gray, dark gray or black. Compared to ‘tri-color’ displays with a red pigment, this display takes a lot less time to update, only about a second instead of 15 seconds!
Adafruit Voice Bonnet for Raspberry Pi -Two Speakers + Two Mics: Your Raspberry Pi computer is like an electronic brain – and with the Adafruit Voice Bonnet you can give it a mouth and ears as well! Featuring two microphones and two 1 Watt speaker outputs using a high quality I2S codec, this Pi add-on will work with any Raspberry Pi with a 2×20 connector – from the Pi Zero up to the Pi 4 and beyond (basically all but the very first ones made).
The on-board WM8960 codec uses I2S digital audio for great quality recording and playback – so it sounds a lot better than the headphone jack on the Pi (or the no-headphone jack on a Pi Zero). We put ferrite beads and filter capacitors on every input and output to get the best possible performance, and all at a great price.
We specifically designed this bonnet for use with making machine learning projects such as DIY voice assistants – for example see this guide on creating a DIY Google Assistant. But you could do various voice activated or voice recognition projects. With two microphones, basic voice position can be detected as well.
