micro bit is an entry level development board designed by BBC for teens programming education. It supports the PXT graphical programming interface developed by Microsoft and can be used under Windows, MacOS, IOS, Android and many other operating systems without additional download of the compiler.
In order to facilitate the wiring of micro bit development board, we specifically design this expansion board. It can be connected to the micro bit development board, then can be directly plugged onto the breadboard.
In the experiment, you can wire it up on the breadboard using jumper wires, pretty easy and convenient.
