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

• 3.6 A Peak Current – Powerful enough for larger brushed DC motors
• 6.5–45V Motor Voltage – Wide input range for diverse applications
• Up to 5.5V Logic – Compatible with 3.3V and 5V microcontrollers
• Resistor-Set Current Limiting – Default ~2 A, adjustable without inline sense resistor
• PWM Control – Built-in PWM support on IN1/IN2 inputs
• Built-In Protections – Undervoltage lockout, overcurrent, and thermal shutdown
• 565 mΩ Typical RDS(on) – Low resistance for efficient operation
