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.
