DRV8825: How adjust the motor current

I have read the docu but can find how to adjust the stepper current correctly.

How should i do this?

Also are on the M0-M2 inputs resistors mandatory or may they be omitted?



Hello, Harry.

You can find instructions for adjusting the current limit of our DRV8825 Stepper Motor Driver Carrier in the “Current Limiting” section of the driver’s product page.

I am not sure what resistors or document you are referencing, but as long as you are supplying a signal between 2.5 and 5.5V, you should not need any additional resistors on the M0-M2 pins. If you want to use the driver in full-step mode, you can leave those pins disconnected. You can find out more about all of the driver’s connections in the “Using the Driver” section of the driver’s product page.
