Introducing the micro:bit Breakout/GPIO expansion board
To extend the functionality of the micro:bit beyond what is already on the board, we developed a micro:bit breakout or General Purpose Input Output (GPIO) expansion board.
This breakout board makes it much easier to use all of the pins available on the micro:bit edge connector in a more user-friendly way. We also broke out ground and VCC (3.3 volts) for your convenience.
The breakout board lines up with the pins of a breadboard. We recommend using a full-sized breadboard with this breakout to give you enough room to prototype circuits on either end of the breadboard. Also, for durability’s sake, insert the breakout pins about halfway into the breadboard so there is support under the board for when you insert a micro:bit and/or pull it out.
Note: Kindly ensure you insert the microbit in the right direction into the breakout expansion board.
