Micro:bit Driver Expansion Board with Extensive Connectivity Options

The micro:bit Driver Expansion Board is your gateway to unleashing the potential of the micro:bit. With a straightforward design and a wealth of connectivity options, this board opens the door to endless creative projects. Whether it's animating a fleet of mini robots, managing servo-powered models, or building a custom interactive device, this board serves as a reliable partner. It leads you to nine micro:bit GPIO interfaces, and its integrated motor drives cater to both standard and stepper motors, providing versatility for various applications.

Featuring an I2C external drive chip, the board simplifies the control of motors and servos, employing just two I2C pins. This design choice ensures you have more resources available for other components and sensors, integral to your intricate inventions. The usage of the HR8833 motor driver offers robustness, withstanding a continuous current of 1.5A, suitable for both small and N20 mini metal motors. With clear indicators for motor direction, users can effortlessly monitor and manage motor operation, making it particularly suitable for crafting precise mechanisms.

The board adopts the DFRobot-Gravity standard interface for extending GPIO and servo connections, immersing users into a universe of compatible modules and sensors. The servo interface's direct link to the Vin power supply enhances the current provision, supporting multiple servos to function concurrently, a feature crucial for complex builds like robot arms or animatronic figures. Additionally, the board welcomes a diverse power supply range from 3.5V to 5.5V, catering to everything from dry battery setups to modern, sustainable power solutions through USB to DC adapters.
