MacroPaw PCB

The MacroPaw keypads are a line of small yet fully-customizable mechanical keyboards. (The name was originally from my son, years ago when he was young, and the "paw" motif has kinda stuck.) The core of the MacroPaws is a Raspberry Pi RP2040 with 16MiB of flash memory, a USB-C connector, and an attached key matrix and RGB LEDs (which may or may not be under the keys). Some MacroPaws have more capability than others; all are crazy customizable by writing Python code. (Yes. Python. On a keyboard. It's insane and wonderful to live in the future.)
