The Cubitpad is a macropad that is designed to maximize functionality in the smallest footprint. It utilizes all pins to their maximum extent on the Seeeduino XIAO RP2040 for the most features, which includes: NKRO 3x3 macro, rotary encoder with push function, and a 0.91" OLED monochrome screen, the keypad also being backlit with neopixels for some flair
To use, one should flash their xiao rp2040 with the correct circuitpython .uf2 file, upload the code file, as well as libraries and linked images, save, and you're good to go! you can customize what each key does, lighting color, text displays, etc all within the code.py file
This was initially created as my own current keyboard lacks a rotary encoder, and I wanted one for volume and other controls, which then spiraled into this project
Friction fitted (with clearance designed for 3d printing)
(I can print this myself, but some filament could be nice)
