Expansion Board for Micro:bit GPIO Expansion Python IO:bit 5V with On Board Passive Buzzer

IO:bit Expansion Board for BBC Micro:bit with Power & Buzzer

The IO:bit Expansion Board is a powerful and versatile expansion board designed for the BBC Micro:bit, providing easy access to all GPIO pins and multiple power options for external modules. The board breaks out 19 Micro:bit I/O pins, with each pin paired with its own VCC and GND, making wiring clean, flexible, and beginner-friendly.

The board supports both 3.3V and 5V power selection via jumper caps, allowing compatibility with a wide range of sensors, actuators, and modules. Dedicated I2C SDA and SCL ports with matching power pins make it easy to connect I2C devices such as LCD1602 displays.

An onboard passive buzzer enables sound output directly from the Micro:bit and can be controlled through MakeCode or MicroPython. With USB and DC power input options, along with status indicators and a compact design, the IO:bit board is ideal for STEM education, robotics, prototyping, and classroom learning.
