The Breadboard breakout for the BBC micro:bit allows the user to plug a BBC microbit into a standard 2.54mm pitch breadboard. Two 11 way pin headers are used to make connections into the breadboard.
The micro:bit slots into the edge connector on the top side of the PCB. No extra tools are required for installation. The front of the BBC micro:bit (the side with the LEDs) should be inserted facing the same side as the 3V pin.
The edge connector has connections on only one side, so if the BBC micro:bit is inserted in reverse orientation, it will not work.
The PCB is designed to plug across the middle slot of a breadboard, the same placement as an IC component.
