Connectors and pin assignment
The EVAL-M3-302F consists of several functional groups, which enable an out-of-the-box, fully functional motor
control system combined with additional interfaces and test points for more advanced use cases.
Key information about the connections of the EVAL-M3-302F evaluation board is described below. Only the USB
interface and the M3 connector to the power board are mandatory, all other interfaces are optional.
