Pinout
The Raspberry Pi Zero V1.3 provides a 40-pin GPIO interface. The GPIO header supports general-purpose digital I/O as well as several hardware communication interfaces. Depending on the board version, the header may be supplied unpopulated and may require separate pin-header installation.

| Interface | Pins / Connector | Function |
|---|---|---|
| GPIO | 40-pin header | Digital input/output and peripheral control |
| I²C | GPIO2 / GPIO3 | SDA / SCL |
| SPI | GPIO7–GPIO11 | SPI communication |
| UART | GPIO14 / GPIO15 | Serial TX / RX |
| Power | 5V / 3.3V / GND | Power and ground connections |
Wiring
External components can be connected to the 40-pin GPIO header according to the required interface. Digital devices can use GPIO pins, while compatible sensors and modules can use the I²C, SPI, or UART interfaces.

The board is powered through its dedicated Micro USB power connector. USB peripherals can be connected through the Micro USB OTG port using a suitable adapter or hub. Displays can be connected through the Mini HDMI connector, while compatible camera modules can be connected through the CSI interface.
