Keyestudio Micro Bit Motor Drive Breakout Board For Micro Bit

The Keyestudio Micro Bit Motor Drive Breakout Board is an expansion board designed to help students, educators, and hobbyists easily drive DC motors using their BBC micro:bit. It simplifies robotics projects by integrating motor driver circuitry and sensor breakout pins onto a single, user-friendly platform. This board is ideal for makers looking to build mobile robots, smart cars, or automated systems without complex wiring.

High-efficiency TB6612FNG driver chip

The board integrates the TB6612FNG driver chip, allowing you to control DC motors with ease. It supports up to 1.2A of continuous drive current per channel, with peak currents reaching 2A to 3.2A.

Flexible motor control modes

Program your mobile robots with precision using four distinct motor control modes: forward, reverse, brake, and stop. The board also supports a high PWM frequency of up to 100 kHz for smooth speed adjustments.

Easy 3-pin sensor expansion

All micro:bit pins are broken out into convenient 3-pin interfaces. This allows you to easily connect external sensors and modules to the board using standard 3-pin wires.

Dual voltage regulated outputs

An onboard voltage-regulator chip steps down the input voltage to provide stable 3.3V and 5V power outputs. This ensures both your micro:bit and external sensors receive clean, regulated power.

Dedicated serial port pins

The breakout board features dedicated serial communication pins to facilitate quick connections. This makes it simple to add wireless control to your project using an external Bluetooth module.

Wide input voltage range

The board accepts a DC input voltage range of 6V to 12V, making it compatible with a variety of battery packs. It measures a compact 70mm by 58mm, fitting easily into small chassis designs.
