Pololu DRV8835 Dual Motor Driver Shield for Arduino

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 1.5V to 11V and makes it particularly well suited for driving small, low-voltage motors. The shield can deliver a continuous 1.2A per channel and tolerate peak currents up to 1.5A 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.

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:

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 not include pass-through, stackable headers. For higher-power drivers with more configuration options, see our larger MC33926 and VNH5019 motor driver shields.

For a higher-voltage alternative to this shield, please consider the dual MAX14870 motor driver shield or A4990 dual motor driver shield. We also have a similar DRV8835 motor driver kit for the Raspberry Pi, as well as a smaller DRV8835 carrier (and an even smaller single-channel DRV8838 carrier) for those using a different controller or with tighter space constraints.

Although the DRV8835 itself works with a minimum motor supply voltage of 0V, this shield’s reverse-protection circuit limits the minimum to 1.5V. If a lower motor supply voltage is required, please consider using our DRV8835 carrier with motor power supplied through the VMM pin.

Features

Dual-H-bridge motor driver: can drive two DC motors or one bipolar stepper motor
Motor supply voltage: 1.5V to 11V
Logic supply voltage 2V to 7V
Output current: 1.2A continuous (1.5A peak) per motor
Motor outputs can be paralleled to deliver 2.4A continuous (3A peak) to a single motor
PWM operation up to 250kHz (ultrasonic frequencies allow for quieter motor operation)
Two possible interface modes: PHASE/ENABLE (default – one pin for direction, another for speed) or IN/IN (outputs mostly mirror inputs)
Shield can optionally power the Arduino base directly when motor supply voltage is suitable
Arduino library makes it easy to get started using this board as a motor driver shield
Arduino pin mappings can be customized if the default mappings are not convenient
Reverse-voltage protection on motor power supply
Under-voltage lockout and protection against over-current and over-temperature
