The board can be powered with 3V3 or 5V.
3V3 operation is only stable with 8MHz. Thus, a prescaler of 2 for the main clock is applied in the early startup of the uC.
+In main.h, set MULTISENSE to define the type of board
+
Each board will get a serial number that is being compiled into the firmware.
It needs to be specified at compile time:
