Voxel Driver Base 16x16 RGB

Drive base for controlling 16 x 16 RGB matrix through PCIE slot.

1 x RP2040 Drives the Column P channel high side FET
3 x RP2040 for sinking current on each row colour

Working on code to pull all this together into a volumetric persistence of vision display.


Boards from JLCPCB arrived and built up a quick prototype assembly with qi coils, RF-300 motor, and a brass shaft coupler.

Qi Coil:

Motor:



IR Sensor:


Shaft Coupler: (2 to 5mm I chose, depends what you mount to)

Solder parts together, then mounted with hotglue because I really wanted to see it light up haha.

Almost looks like a Christmas tree running some buggy unsync'd code

 **Improvements to be made **:
1. use the hardware uart # properly on the column driver chip for potentially better performance
