This add-on board enables a Raspberry Pi B+, Pi A+, Pi 2 or Pi 3 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.
