motor:bit Introduction
Introduction
Motor:bit is a motor driving board based on micro:bit. It has integrated a TB6612
motor driving chip, which is used to drive two motors with maximun 1.2A DC single
channel current. It has also integrated 12 GVS ports(for connecting OCTOPUS series
of electric bricks) and 1 IIC communication port. These ports allow you to extend
with various sensors and electric modules. On the board, P3-P7, P9-P10 are IO ports
for directly driving 3.3V devices; P13-P16, P19-P20(IIC port) support 3.3V/5V
voltage switch. Sliding the voltage switch onboard, it is available to drive 3.3V or 5V
devices. Besides, you can play music with the buzzer on motor:bit. Motor:bit is
totally designed for DIYers. You can use it to create your own smart car or more
funny projects.
