Hello,
I have this motor driver. It was working fine, but suddenly it only turns in one direction. I checked the dc voltage from ESP32 board that feeds the signal to the DIR pin. When the DIR signal steps between 0V and 3.3V, the output polarity to the DC motor does not change. Most likely I have blown the driver. Is there a fix for this, other than tossing it out ?
Thanks
Hello.
The first thing to check is that there is not something wrong with your connections. Can you post some pictures that show your connections as well as close-ups of the soldering? If you have not already, can you measure the voltage at the DIR pin on the driver to make sure you are actually seeing the change there?
