Overview
General
The VMM403 motor driver breakout board integrates the TB6612FNG chip and gives your micro:bit the ability to drive two channel DC motors. Each channel can output up to 1.2 A continuously with peak current up to 2 A. There are 4 motor control modes: forward, reverse, brake and stop. The PWM supporting frequency is up to 100 kHz. The micro:bit pins are broken out into 3-pin headers for easy access and the integrated voltage regulator provides 3.3 V and 5 V power output. This breakout board is ideal if you want to start with robot projects!
