Using a Raspberry Pi Pico running CircuitPython with a Pimoroni RGB Keypad you can code a macro keypad that appears as a keyboard to a PC and use it to do media control or key macros.
But those RGB's are crying out to make pretty patterns rather than just a boring light up when you press them.
I really like that the Pico is on display too (we don't want to hide that beauty) :)
