BBC micro:bit is a pocket-sized codeable computer with motion detection, a built-in compass and Bluetooth technology.
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 .
Battery Voltage：DC 1.5V
Input Voltage：DC 3V
