Pimoroni Keybow family
A family of macro pads based on raspberry pi hardware:  (Original) Keybow - Raspberry Pi hat. 4x3 hotswap keys, with an APA102 LED per key.
 Keybow 2040 - custom RP2040 board. 4x4 hotswap keys, with an RGB LED per key driven by a shared IS31FL3731 controller.
These boards share the 'feature' of using a single GPIO per key rather than a row and column matrix, so these both
use CircuitPython's keypad.Keys
module instead of the regular KMK matrix scanner.
