| 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. |
| |
