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!

When using rechargeable NiMH the output voltage will range from about 2.7V with...
