radds board alternative laser pin


Somehow the sparkLCD adapte for 12864 display is not working anymore.
When vonnected without the adapter its working but taling up all pins on  the radds AUX 1 connector.

Is there another pin I can use for controlling the laser?
Maybe one of the servo pins?



  • All pins directly connected to cpu can be used including servo pin if we are talking about a 3.3V output signal. Just ensure no other function is assigned to that pin. So servo pin is ok if no servo is configured to use it.
