NewImage 43 1 1 1


We’ve got so much happening here at Adafruit that it’s not always easy to keep up! Don’t fret, we’ve got you covered. Each week we’ll be posting a handy round-up of what we’ve been up to, ranging from learn guides to blog articles, videos, and more.


Testing out QT Py RP2040 with Xiao Extension Board

This Expansion board is designed for the Seeed Xiao, and since the QT Py is pin compatible we thought we’d try it out with the RP2040 QT Py we just released to see how it works with CircuitPython. The RP2040 has toooons more flash and RAM than the SAMD21 so it’s a great little add-on! There’s a 128×64 OLED, button, piezo beeper, battery charger and booster, SD card and RTC.

Keeping with tradition, we covered quite a bit this past week. Here’s a kinda short nearing medium length list of highlights:


Lemon Mechanical Keypad

Make a custom USB-HID keypad in the shape of a citrus fruit. This keypad features six mechanical switches for controlling media players like Spotify, iTunes, YouTube, etc. Powered by the Adafruit QT Py RP2040 and CircuitPython.

Inside the case is a NeoPixel Jewel that slowly fades in and out making the keypad illuminate. The QT Py and NeoPixel are housed in a 3D printed case with parts that snap fit together.
