Hardware:

MCU - Teensy 4.0

RGB OLED - SPI

WS2812B RGB LEDs

The board uses a daughter board to attach the RGB LEDs.

Buttons and DIP switches in the back allow for USER profiles to be programmed in.

Case:

3D printed PLA case. Consists of the main case to mount the PCB, plate to mount switches, and a shield for the screen.

Main case uses threaded inserts to screw in the PCB.
