Motor:Bit Board
Introduction
Motor:bit is a motor driving board based on micro:bit. It has an integrated TB6612 motor driver chip, which is used to run two motors with maximum 1.2A DC per single channel. The board also has the ability to change 6 ports from 3V/5V.
Ports P3-P7, P9-P10 are IO ports for directly driving 3.3V devices
Ports P13-P16, P19-P20(IIC port) support 3.3V/5V voltage switch
Sliding the voltage switch onboard, toggles the ports from 3.3V to 5V for some devices.
Why would you need to change
Extensions - Software Programming
Click “Advanced” in the MakeCode to see more choices.
Next click "Extensions"
Type "motorbit" within the search box.
This will display the "Motorbit" Library that you can click on and install
DC Motor Connector
Connectors shown as M1 and M2 can support a DC motor with a max current of 1.2A.
Buzzer
Once a passive buzzer is connected to the P0 port on micro:bit, it can play music.
Power Switch
Slide the switch to ON, power is connected; slide the switch to OFF, Power is disconnected.
External power connector for motor support
The power connector is available to provide 6-12V DC power to the motor ports. Please keep in mind that the motor ports can not support AMPS higher than 1.2 so no big motors:().
Pin Voltage Switch
Sliding the switch from 5V to 3.3V will change the 6 IO ports only: P13, P14, P15, P16, P19, P20 from 3 to 5 volts.
