This compact expansion board plugs directly into the GPIO header on a Raspberry Pi B+, Pi A+, Pi 2, or Pi 3 and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Its integrated DRV8835 dual motor driver allows it to operate from 1.5 V to 11 V, making it a great control option for low-voltage motors. The board can deliver a continuous 1.2 A (1.5 A peak) per motor, or a continuous 2.4 A (3 A peak) to a single motor when configured with both channels connected in parallel.

Dimensions
Size: 1.7″ × 0.65″1
Weight: 2.3 g1


General specifications

  • Motor driver: DRV8835
  • Motor channels: 2
  • Minimum operating voltage: 1.5 V2
  • Maximum operating voltage: 11 V
  • Continuous output current per channel: 1.2 A3
  • Peak output current per channel: 1.5 A
  • Continuous paralleled output current: 2.4 A3
  • Maximum PWM frequency: 250 kHz
  • Reverse voltage protection?: Y

Notes:
1 Without included hardware.
2 The DRV8835 itself has a minimum motor supply voltage of 0 V, but the board's reverse-voltage protection circuit limits the minimum to 1.5 V.
3 Typical results with 100% duty cycle at room temperature.
