How it works

Input and Output

Normal connector and Quick connector is parallel. ONLY ONE CONNECTOR REQUIRED AT ONE TIME.



Micro-stepping Setting

This picture shows how you can change the micro-stepping settings of the driver.



Output Limit current Adjust

You can approximate the current limit by the position of the marked point on the trimmer. DO NOT EXCEED YOUR MOTOR’S CURRENT RATING.

OR the current limit can be adjusted by measuring VREF and turning the trimmer. Connect the [+] of the voltmeter to VREF and the [-] lead to GND and read the value.

Current Limit = VREF ÷ 0.6801

So for example the Max current is: 2.81V ÷ 0.6801 = 4.1317A
