Raspberry Pi 2 Gpio Pins

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.

Raspberry pi 2 gpio pins. Micro sd card if you re using a raspberry pi 2 3 or 4 8 gb recommended ethernet cord or wifi dongle only if you re controlling. If you re using the raspberry pi b 2 zero 3 or the latest raspberry pi 4 model b you ll discover that your board have a total of 40 gpio pins. The comprehensive gpio pinout guide for the raspberry pi. A powerful feature of the raspberry pi is the row of gpio general purpose input output pins along the top edge of the board.

It also includes dozens of pinouts for raspberry pi add on boards hats and phats. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins. 1x i2c bus. The raspberry pi has two i2c connections at gpio 2 and 3 sda and scl are for i2c0 master and physical pins 27 and 28 are i2c pins that enable the pi to talk to compatible hat hardware.

Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. 2x 3 3v. 5 minutes to read. The pi either uses a 40 pin or 26 pin depending on the model and it is important to understand how those pins are arranged and labelled.

2x 5v power pins. Knowing the power limitations of the gpio pins and also understanding what you re plugging in is a must. The gpio header provides the following power and interface options. 3 3v on 2 pins 5v on 2 pins ground on 8 pins.

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. Support pinout xyz on patreon. Raspberry pi 2 3 pin mappings. The equipment that i use in this raspberry pi gpio tutorial is listed below.

The raspberry header is the key to its ability to interface with the real world.
