Got this board off you to drive 2 DC geared motors 24v-3a using an aduino uno to code. one motor works fine going both forwards and back however one of the motors will only go in one direction. i changed the polarity manually to check it wasn’t a problem with the motor but for some reason i cant get it to work in both directions.
Hello,
Which VNH5019 board are you using? How you are powering the driver? Are you using our Arduino library and the unmodified example code? If you are using our VNH5019 shield, can you try using our example with no motors attached and checking that it cycles between turning on the red and green LED on each side? Can you post pictures of your setup that show all connections including soldering?
