Current issues

  • There is no clear marking on the pcb which revision it is.
  • Add silkscreen labels to connectors.
  • LED3 (indicator for 2.5v reference) is breaking the reference voltage cause it is drawing too much current.
  • Pin 0 is used for the reset of the LED driver, but if there is Serial communication it is on pin 0 and 1 so it resets the led driver. Jure made a fix by desoldering r24 and soldering a wire from pin 2 to the led drive side of pad r24.
  • Mounting holes are not perfectly square
  • Arduino reset button is hard to reach
