Hello,
I have bought a A4988 motor driver. Im trying to use it with my arduino Nano IoT.
I recently bought a clone A4988 driver, but they were faulty. So I bought them from Polulu.
Unfortunately, I can’t get them to work at all now.
Please find the attached wiring diagram.
I’m not reading any voltage on the motor pins - the coils are not getting powered.
I have measured VMOT + GND and VDD + GND.
Both receive voltage.
Attached a picture of my soldered A4988. Seems like the Motor Driver is faulty?
Thank you for your help.
