Adafruit DRV8871 DC Motor Driver Breakout Board - 3.6A Max
100 units available with a short lead time.
The Adafruit DRV8871 is a single-channel brushed DC motor driver breakout capable of delivering up to 3.6 A peak current with a wide 6.5–45V motor voltage range. Its resistor-set current limiting and built-in PWM support make it straightforward to use with virtually any brushed DC motor.
The board includes a 30K current-limiting resistor (pre-set to ~2 A), which can be removed or changed to adjust the limit. Built-in protections include undervoltage lockout, overcurrent protection, and thermal shutdown. Simply connect your motor to the output terminals, supply 6.5–45V DC, and control direction/speed via two logic inputs.
Key Features
