This motor driver shield and the associated Arduino library make it easy to control a pair of bidirectional, gebürsteter DC motors with an Arduino or a compatible board, such as the A-Star 32U4 Prime.
On the board is the DRV8835 Dual-H-Bridge motor driver IC from Texas Instruments, which makes it possible to work from 1.5 V to 11 V and makes it particularly suitable for operating small low-voltage motors. The shield can provide a continuous 1.2A per channel and tolerate peak currents up to 1.5A per channel for a few seconds, and the channels can optionally be operated in parallel to provide double the current to a single motor.
The shield is supplied fully assembled with its SMD components, including the DRV8835 driver and an FET for reverse polarity protection.
Pin plugs for connection to an Arduino and terminals for connecting motors and power are included, but not included. The shield uses the digital pins 7, 8, 9 and 10 for its control lines, whereby the assignment of the control pins can be adjusted if the default settings are not suitable.
two possible interface modes:
- PHASE/ENABLE (default - one pin for direction, another for speed) or
- IN/IN (output mostly mirror input)
Shield can optionally supply power directly to the Arduino base if the motor supply voltage is suitable. The Arduino library makes it easy to start using this board as a motor driver's shield. Arduino pin mappings can be customized if the standard mappings are not suitable.
- Reverse polarity protection at the motor power supply
- Undervoltage block and protection against overcurrent and overtemperature
Dual-H bridge motor driver: can drive two DC motors or one bipolar stepper motor.
- Motor supply voltage: 1.5 V to 11 V
- Logic power supply voltage: 2 V to 7 V
- Output current: 1.2 A continuous (1.5 A peak) per motor
The motor outputs can be connected in parallel to deliver 2.4 A continuous (3 A peak) to a single motor.
PWM operation up to 250 kHz (ultrasonic frequencies allow quieter motor operation)
