This add-on board enables a compatible Raspberry Pi (Model B+ or newer), including the Pi 3 Model B+ and Model A+, to drive a pair of brushed DC motors | Its dual MC33926 motor drivers operate from 5 V to 28 V and can deliver a continuous 3 A (5 A peak) per motor | The default pin mappings make it easy to get started using our provided software, but the board also exposes most of the driver chips’ I/O pins for more specialized applications | This version ships as a partial kit; all surface-mount components are installed, but the included through-hole connectors are not soldered in
