DRV8835 Dual Motor Driver Shield for Arduino

Description

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. This 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 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 shield ships fully populated with its SMD components, including the DRV8835 driver and a FET for reverse battery protection; header pins for interfacing with an Arduino and terminal blocks for connecting motors and power are included but are not soldered in (see the Assembly with included hardware section below). The shield uses digital pins 7, 8, 9, and 10 for its control lines, though the control pin mappings can be customized if the defaults are not convenient. It should be compatible with any board that has a standard Arduino pin arrangement and the ability to generate PWM signals on pins 9 and 10. Compatible control boards include: A-Star 32U4 Prime Arduino Uno Arduino Leonardo Arduino Due Arduino Mega 2560 This shield is intended to provide a low-cost, basic motor driver option for Arduinos, so it is much smaller than typical Arduino shields and does no
