| The Raspberry Pi has ported out some General-Purpose Input/Output (GPIO) lines. Several lines share functionality across the board's peripherals. To access peripherals like GPIO, they must be enabled in the Raspberry Pi 5 OS. Many things can be done with the Raspberry Pi's available GPIOs. In the picture below, the GPIOs and their alternative functions (in scope) are shown. | The Raspberry Pi has ported out some General-Purpose Input/Output (GPIO) lines.
