Pololu DRV8835 Dual Motor Driver Shield for Arduino

This small shield is an easy, economical way to control two small brushed DC motors with an Arduino or Arduino-compatible board. Its integrated DRV8835 dual motor driver allows it to operate from 1.5 V to 11 V, making it a great control option for low-voltage motors. The shield 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.
