Checking if A4988 is burned out

Can u plse help me to know whether A4988 driver has been burned or not. I was doing the control of stepper motor with its driver…Instead of 12V power supply, i gave 15V supply. Will it be spoiled or not…I have used 100microfared capacitor while connecting it with the power supply…Can u give reply as soon as possible.


I moved your post to a new thread to keep the discussion better organized.

The A4988 can operate with voltages up to 35V, so supplying it with 15V should not have damaged anything. Is your driver not working somehow?
