Dual Motor Driver Kit for Raspberry Pi DRV8835

Note: The Raspberry Pi shown in these images is NOT included.

Overview

This motor driver kit and its corresponding Python library make it easy to control a pair of bidirectional, brushed DC motors with a Raspberry Pi Model B+, Model A+, or Pi 2/3 Model B.

The expansion board features Texas Instruments’ DRV8835 dual H-bridge motor driver IC, which allows it to operate from 1.5 V to 11 V and makes it particularly well suited for driving small, low-voltage motors.

The board can deliver a continuous 1.2 A per channel and tolerate peak currents up to 1.5 A per channel for a few seconds, and the channels can be optionally configured to run in parallel to deliver twice the current to a single motor.

The board ships fully populated with its SMD components, including the DRV8835 driver and a FET for reverse battery protection; header pins for interfacing with a Raspberry Pi and terminal blocks for connecting motors and power are included but are not soldered in (see the Assembly with included hardware section below).
