Adafruit DRV8871 DC Motor Driver Breakout Board - 3.6A Max
All prices are VAT included
Crank up your robotics with powerful Adafruit DRV8871 motor driver breakout board . This motor driver has a lot of great specs that make it useful for a wide variety of mechatronics. In particular, the simple resistor-set current limiting and auto-magic PWM support make it super easy to use with just about any brushed DC motor.
Check out the specs for the DRV8871:
- 6.5V to 45V motor power voltage
- Up to 5.5V logic level on IN pins
- 565mΩ Typical RDS(on) (high + low)
- 3.6A peak current
- PWM control
- Current limiting/regulation without an inline sense resistor
- Undervoltage lockout
- Overcurrent protection
- Thermal shutdown
Using it is super simple. Connect your motor to the OUT terminal block. Power the board with 6.5-45VDC power on VMotor and provide the H-bridge input control on IN1 and IN2 . You can even PWM the inputs and the driver chip will do the right thing.
You can set the current limiting with an external resistor Rlim . We solder in a 30K resistor by default for a ~2A current limit, however you can remove this resistor and/or solder a resistor over it to change the resistance and change the limit.
Each order comes with one fully assembled and tested motor driver breakout, two 2-pin terminal blocks and a small strip of header. Some light soldering is required to attach the header and terminal blocks but it's a simple task that can be done with basic soldering equipment.
Note: The terminal blocks included with your product may be blue or black.
