Introduction

 

ELECFREKAS Motor:bit

 is a kind of motor drive board based on micro:bit. It has integrated a motor drive

chip TB6612, which can drive two DC motors with 1.2A max single channel current. Motor:bit has
integrated Octopus series’ sensor connectors. You can plug various sensors into it directly. Among these
connectors, P0, P3-P7, P9-P10 support sensors with 3.3V power voltage only; P13-P16, P19-P20 support
3.3V or 5V sensors. You can change electric level by sliding the switch on the board.
