Hi, here a fork project from David Madison. Full details : @link partsnotincluded.com/electronics/diy-stream-deck-mini-macro-keyboard
A arduino Pro Micro is required (with ATmega32U4 on board).
I added a oled screen and support leds inside. LEDs are triggered by a non touch button (TTP223 button) with 6 light modes.
