Introduction
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. On-board comes with two interfaces, which can access to two-cell batteries, each supply 1.5V. It also comes with a DIP switch for controlling the power input.
In the experiment, you can connect the expansion board and micro bit development board using a double-headed JST-PH2.0MM-2P 24AWG red-black wire to supply power for micro bit development board .
