Decription:

Drive current algorithm: i = Vref * 1.9/2.5, the default Vref is about 0.65v, so the default current is 0.5A, the maximum current is 1A!

Vref measures Gnd and the voltage at the middle of the potentiometer.

Do not connect the motor when measuring voltage, otherwise it is easy to burn the driver.

The power should be turned on when measuring the voltage. Do not connect the USB power supply only.

1. When using on Ramps 1.4 or MKS Gen, please remove the three jumper caps under the socket

2, pay attention to the direction
