Parker couldn’t find suitable motor driver board for TI Launchpad, so he started his own project. Since Launchpad works on 3.3V signal levels, DRV8833PWPR dual H-bridge motor driver chip seemed proper choice. It can handle 2 A load per motor and work from voltages 2.7V to 10.8V.
Chip has a nSleep pin that can be used to put driver in to sleep mode in order to preserve energy. This is really nice and simple open hardware motor board to use with smaller motors in hobby projects.
