MC Workbench is not configuring OPAMP3 but PB0, PB1 and PB2 are configured for OPAMP3 inputs and output in eval board .

Hi @FYurt.1​ ,

I confirm that, from the hardware point of view, the board can use the OPAMP3 for the current sensing.

However, this option is not natively supported by the motor control library at the moment and the dual opamp solution is proposed instead.

This option is listed in the table you can find in sheet 3 of the schematic and requires no changes at PCB level.
