micro: IO-BOX Expansion Board with Li-ion Battery Power for micro:bit

The micro: IO-BOX is a compact expansion board designed to expand the connectivity and power options of your micro:bit. Equipped with onboard motor drivers, multiple breakout pins, and integrated rechargeable Li-ion battery power, it is well suited for students, makers, and educators building portable robotics projects.

Rechargeable Li-ion battery power

The expansion board incorporates rechargeable Li-ion battery power to run your micro:bit and connected components without requiring tethered USB cables.

Dual-channel motor driver

An onboard 2-channel motor driver provides direct control for two DC motors, making it simple to construct compact mobile robots.

Versatile IO and UART ports

The board features 9 general-purpose IO ports alongside a dedicated UART interface for connecting external sensors, actuators, and serial devices.

Dual I2C expansion interfaces

Two onboard I2C ports allow you to connect multiple I2C-compatible sensors, displays, and breakout modules simultaneously.

Integrated onboard buzzer

A built-in buzzer provides direct audio output for playing tones, melody generation, and system feedback without extra wiring.

Compact micro:bit form factor

Engineered with a compact footprint, the board neatly mounts the micro:bit to form an all-in-one control unit for space-constrained builds.
