Development Boards / micro:bit Add-ons & Compatibles

The British Invasion is here! No, not music...microcontrollers! Designed specifically for kids and beginners, the BBC micro:bit is a pocket-sized computer that you can code, customize and control to bring your digital ideas, games and apps to life. It’s a small, code-able device that is a non-intimidating introduction to programming and making – switch on, program it to do something fun – wear it, customize it, develop new ideas. It's one of the easiest ways to learn programming and electronics!

Over the last few years there have been tons of accessories, add-ons, and other devices that use the micro:bit-style edge connector too! Not all things work together, so make sure you review the product pages for what works with what and what software support there is!

2x40 Right Angle Edge Connector for micro:bit

Product ID: 3342

This is a connector that fits directly to the edge contacts of a BBC micro:bit.

Also, the back half of the pins are not used at all. The edge connector gives access to all the important pins...
