Driver current regulation:
1:Verf measures the voltage of Gnd and potentiometer middle.
2:Please DO NOT connect the motors when measuring the voltage, or it's easy to burn the drive.
3:Please connect the power supply when measuring voltage as well, do not connect only the USB power.
4:Please pay special attention to the direction, do not insert wrongly!
Driver current algorithm:
I=Vref Default I=1.25A
