Raspberry Pi 3 B Gpio Pins Layout

Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.
Raspberry pi 3 b gpio pins layout. In order to avoid damaging your pi you need to be sure what pins you are connecting to other hardware and that your program is referring to the correct pins. Pi hardware raspberry pi 1 model b model b io pins note that we are not currently sure if the new pin 27 40 pwm1 gpclk1 and gpclk2 peripheral pin functions will be made accessible under raspbian and if so which pins they will be assigned to hence the duplicated pins shown with these functions. Raspberry pi gpio layout model b one of the most significant changes to the raspberry pi model b is the 40 pin header j8. The raspberry pi 3b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins.
Raspberry pi 2 3 pin mappings. Pins 1 2 39 40 are also labeled below j8 pinout 40 pin header. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. 5 minutes to read.
This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces. 24x gpio pins. The header provides 5v on pin 2 and 3 3v on pin 1. 1x i2c bus.
Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. 2x 5v power pins. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program.
Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. The genesis of the raspberry pi came from a few college students concerned about the dwindling number and skills of students applying to study computer science. Newer computers and game consoles have replaced the old machines where most of us learned to program. 2x 3 3v.
To confuse things even more the gpio pins are sometimes renamed with another set of numbers. The raspberry pi gpio pinout guide. If you love pinout please help me fund new features and improvements.
