    GPIO pins exposed on BBC MicroBit headers.

    The edge connector on the micro:bit is used to connect to external
    circuits and components.

    There are 25 strips/pins including 5 rings for using with 4mm banana
    plugs or crocodile clips. 3 of these rings are for general purpose
    input and output (GPIO) and are also capable of analog, PWM and touch
    sensing, and two are connected to the micro:bit power supply.

    The smaller strips spaced at 1.27mm on the edge connector have additional
    signals, some of which are used by the micro:bit, and others that are free
    for you to use. There are a number of external PCB connectors for purchase
    with an 80w 1.27mm pitch that can be used to easily access these extra pins.

    Only the pins on the front are connected to signals. The back rings are
    connected to the front rings, but the back small strips are unconnected.
