A Raspberry Pi has 26 GPIO pins. These allow you to send and receive on/off signals to and from electronic components such as LEDs, motors, and buttons. If you look at a Raspberry Pi with the USB ports facing towards you, the layout of the GPIO pins is as follows.

Feb 14, 2025 · On a Raspberry Pi, the GPIO pinout refers to the map of pins on the board that can be used to connect and control external devices. Each pin can be set as an input or output, allowing interaction with various sensors and accessories.

Compute Module models feature hardware equivalent to the corresponding flagship models, but with fewer ports and no on-board GPIO pins. Instead, users should connect Compute Modules to a separate baseboard that provides the ports and pins required for a given application.
