Pololu DRV8835 Dual Motor Driver Kit for Raspberry Pi B+

This compact expansion board plugs directly into the GPIO header on a Raspberry Pi B+ and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Its integrated DRV8835 dual motor driver operates from 2 V to 11 V, making it a great control option for low-voltage motors. The board can deliver a continuous 1.2 A (1.5 A peak) per motor, or a continuous 2.4 A (3 A peak) to a single motor when configured with both channels connected in parallel.
