BMT Micro:bit Breakout Adapter - GPIO Extension Expansion Board

The BMT Micro:bit Breakout Adapter is a practical and versatile GPIO extension board designed specifically for the BBC micro:bit. This expansion adapter makes it easy to access and use all available micro:bit GPIO pins, transforming the compact gold-finger edge connector into a standard 2.54mm pin header layout suitable for breadboards, jumper wires, and external modules.

Ideal for education, prototyping, and rapid development, this breakout board simplifies hardware connections and allows users to focus on learning, experimentation, and project creation without dealing with complex wiring or custom adapters.

Product Overview

The micro:bit Breakout Adapter plugs directly into the micro:bit's gold finger edge connector, securely exposing all 21 GPIO pins in a clearly arranged and breadboard-friendly format. Once connected, every GPIO can be easily accessed using standard jumper wires, sensors, actuators, and electronic components.

This makes the board perfect for classroom use, STEM education, robotics projects, and hobby electronics, where quick setup and reliable pin access are essential.
