[ADI TMC2208 stepper motor evaluation board] Part 4: Choosing the right drive current [Copy link]

ADI TMC2208 stepper motor evaluation board can adjust the drive current through the sliding resistor

When the reference voltage is 1.34V, the stepper motor heats up severely

The fever temperature reaches about 97℃

By adjusting the sliding rheostat, when the reference voltage is 0.1V, the stepper motor heats moderately

Fever temperature is around 51°C
