Check your software. Do not switch too fast from 127 to 255. This will create a current surge in the controller, and over time, damage the controller. It is always better to pass through (127) briefly before changing direction, or gradually increase the speed from 127 to the desired speed. Do not make the $120 mistake. You will not even notice the slower transition either, since we are talking milliseconds in delay times.

Red actually means full reverse, not a problem with the 884, just wanted to make sure the LED color signals were clear.
