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 = Vref Default I = 1.25A
