Driver current regulation:

Verf measures the voltage of Gnd and potentiometer middle.
Please DO NOT connect the motors when measuring the voltage, or it's easy to burn the drive.
Please connect the power supply when measuring voltage as well, do not connect only the USB power.
Please pay special attention to the direction, do not insert wrongly!

Driver current algorithm:

I=V_ref Default I=1.25A

Notice:

Pay attention to the connection direction,do not reverse it.
The motor direction is opposite to that of A4988 and DRV8825, please adjust the firmware or adjust the motor wiring if you want to change A4988.
