Raspberry Pi 2 Model B Gpio Layout

This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces.
Raspberry pi 2 model b gpio layout. Raspberry pi 2 3 pin mappings. A raspberry pi gpio layout pi 1 model a b revision 2. The original 26 pin gpio header. Gpio pinout rasp pi 1 model b rasp pi 2 model b.
Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.
5 minutes to read. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. The raspberry pi 2 model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. 1x i2c bus.
24x gpio pins. Locate p1 and compare the header to. 2x 3 3v. It consists of two rows of thirteen pins.
Gpio pinout rasp pi 1 rev1 and rev2. 2x 5v power pins. 1x serial uarts rpi3 only includes mini uart 2x spi bus. Pin 1 is clearly marked on the board as p1.
It is vital you are looking at the header the correct way round. And faster interfaces is a strong competitor for the raspberry pi. Pinout also includes dozens of pinouts for raspberry pi add on boards. Pi 1 model b revision 1 0 this is where it all began.
