Facility Safety and the Personal Safety:
Please add a fuse@20A between the Power source and this shield.

Installation Tips

The back of the driver board has some large bare traces. It is important to make sure that these do not get shorted out against conductive surfaces of your project. Please measure carefully and if needed, apply 1mm of non-conductive epoxy to protect the board.

Pluggable Connector

The connectors are designed to be pluggable. This allows you to attach wires with male or female terminations.

Result

You should see your motor run forward for 3 seconds and then run reverse for another 3 seconds and then repeat.
