Five Ring Input and Output (I/O) including power (PWR) and ground (GRD). PWR, GRD, I/O x 3. Each I/O ring is programmable to be either analogue or digital. The rings are suitable for crocodile clips or 4mm banana plugs, meaning an external sensor can be connected to measure things like temperature, moisture, proximity to other devices. The PWR and GRD rings supply 3 volts and could be used to power a separate device.
Edge Connector: 20 pins, 1.27mm pitch and extend 7.62mm from board edge suitable for standard connectors. This allows the micro:bit to be connected to another device, eg Arduino, Galileo, Kano and Raspberry Pi through a standard connector.
Micro-USB controller: This is controlled by a separate processor and presents the micro:bit to a computer as a memory stick. This means the program can be dragged onto the micro:bit in the same way a file is dragged onto a memory stick.
