 ### Power considerations
 The power connector has two positive voltage rails, one for power outputs for motors and the second for control logic (MCU etc..). The power board should include a step-down 5V converter which will power the MCU board. The MCU board should by default be powered by 5V (we want the MCU board to be also powered from USB source). The MCU board should include a step-down 3.3V converter for powering the ATSAMV71.

+This is mandatory, so these pins should not be occupied by anything else.
