DFRobot DFR0548 Micro:bit Driver Expansion Board
DFRobot DFR0548 Micro:bit Driver Expansion Board features nine micro:bit onboard GPIO interfaces, 4-way motor drives, and eight servo interfaces. The 4-way motor drives can also be reused as 2-way stepper motor drives. This expansion board adopts IIC external drive chip to control the motor and servo motor. The DFR0548 expansion board uses the HR8833 motor driver to drive N20 mini metal motor or any ordinary small motors. Each motor port has a positive and negative rotating indicator to identify the motor running direction for helping students/designers do small projects. This micro:bit driver expansion board supports a 3.5V to 5.5V power supply and comes with a USB to DC 2.1 adapter cable.
