Raspberry Pi 3 B Gpio Map

2x 5v power pins.

Raspberry pi 3 b gpio map. Explaining the raspberry pi gpio pinout ref. 24x gpio pins. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. The new b has 26 ports available for gpio work.

If you love pinout please help me fund new features and improvements. Raspberry pi 40 pin gpio header. Print it optionally laminate it poke some holes in it and slip it over the gpio pins of your raspberry. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins.

1x serial uarts rpi3 only includes mini uart 2x spi bus. The majority of raspberry pi models use the same 40 pin header. The top 26 pins are all the same but the 14 new pins contain 9 gpio ports. Raspberry pi gpio layout model b one of the most significant changes to the raspberry pi model b is the 40 pin header j8.

5 minutes to read. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. I wanted to check out the gpio ports on the raspberry pi b. Pwm pulse width modulation i2c.

Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. 3 3v 1 2 5v 3 3v 1 2 5v 3 3v 1 2 5v gpio0 3 4 5v gpio2 3 4 5v gpio2 3 4 5v gpio1 5 6 gnd gpio3 5 6 gnd gpio3 5 6 gnd gpio4 7 8 gpio14 gpio4 7 8 gpio14 gpio4 7 8 gpio14. 2x 3 3v. Generally the one that s most convenient or closest to the rest of your connections is tidier and easier or alternatively the one closest to the supply pin that you use.

The raspberry pi gpio pinout guide. 1x i2c bus. The ground pins on the raspberry pi are all electrically connected so it doesn t matter which one you use if you re wiring up a voltage supply. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.

Inspired by the original rasperry leaf but for the 40 pins of a raspberry b. Makes working with it much easier. Raspberry pi 2 3 pin mappings. There s a full explanation of the ports in the diagram here.

Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. Raspberry pi b pinout leaf. 3 3v on 2 pins 5v on 2 pins ground on 8 pins general purpose input and output. 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 previous model b had 17 on the main p1 header and four more on the now deleted p5 header. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board.
