DFR0548

micro:bit driver expansion board adopts I2C external drive chip to control the motor and servo motor. Only takes up two I2C pins and can complete the motor and servo dual control without occupying other resources. Using HR8833 motor driver, the maximum continuous operating current is 1.5A, it can drive the ordinary small motor and N20 mini metal motor. Each motor port comes with a positive and negative rotating indicator to identify the motor running direction conveniently which is very suitable for students and makers to make small projects. Both the extended GPIO and the servo interface use the DFRobot-Gravity standard interface, supporting a large number of modules and sensors. The servo interface is directly connected to the Vin power supply, thus increasing the supply current which can support multiple servos to work at the same time.
