Raspberry Pi 2 Gpio Map

The comprehensive gpio pinout guide for the raspberry pi.

Raspberry pi 2 gpio map. 1x i2c bus. Version 1 5th february 2020. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. The pi wants 3 3v i o so the board includes a logic level converter to drop the 5v signals from the keyboard to 3 3v.

Pwm pulse width modulation i2c. Bcm2711 arm peripherals raspberry pi trading ltd. The board is designed to be like a hat so you can plug the board to the gpio header but still have access to all of the gpio lines. In many outdoor applications especially those that move car pc weather balloon etc the exact position is a big advantage.

2x 5v power pins. On the raspberry pi model 3b the hardware based serial uart device dev ttyama0 has been re purposed to communicate with the the built in bluetooth modem and is no longer mapped to the serial rx tx pins on the gpio header. This gpio pinout is designed to be both a quick and interactive reference to the raspberry pi gpio pins plus a comprehensive guide to your raspberry pi s gpio interfaces. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board.

Here s a map and detailed explanation of what each does including on the pi 4. It also includes dozens of pinouts for raspberry pi add on boards hats and phats. The majority of raspberry pi models use the same 40 pin header. Mobility is achieved with a battery pack or a usb power bank.

The raspberry pi has 40 gpio pins that connect to sensors lights motors and other devices. 24x gpio pins. Raspberry pi 40 pin gpio header. Raspberry pi 2 3 pin mappings.

Support pinout xyz on patreon. 5 minutes to read. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Almost all hardware devices show up in physical memory somewhere.

1x serial uarts rpi3 only includes mini uart 2x spi bus. The adapter maps the clock and data lines from the keyboard to two raspberry pi gpios. On the raspberry pi single board arm computer the external pins called general purpose input output gpio pins are accessible to the cpu as a range of physical memory addresses. 2x 3 3v.

These allow a massive range of sensors motors leds and accessories to be connected to the pi. While every smartphone has gps the pi can also be converted into a gps receiver with a cheap raspberry pi gps module.
