Pololu DRV8835 Dual Motor Driver Shield for Arduino _JAN26CLR The board uses an optocouplerThis motor driver shield and its corresponding Arduino library make it easy to control a pair of bidirectional, brushed DC motors with an Arduino or compatible board, such as the A Star 32U4 Prime. The 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 shield can deliver a continuous 1. 2 A per channel
