3.3. Interface Connector

The interface connector (J11 and J12) is the signal interface between the 3-phase inverter
board and the controller board, see
connections are used as IOs or monitoring. In addition, the 3-phase inverter board current
consumption and IO reference voltage are also connected.
There is a main supply voltage interface connector (J10) for VIN that is used to power the motor
controller board. This will go to the Buck converter stage on the motor controller board described in
Section
