Model b raspberry pi gpio pinout. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program. By matt on july 18 2014 model b. The raspberry pi model b board revision 2 0 contains both a 26 pin expansion header labeled as p1 providing access to 17 gpio pins and an 8 pin expansion header labeled as p5 providing an additional 4 gpio pins for a total of 21 gpio pins. What each pin does on pi 4 earlier models.

The raspberry pi 3 model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. Feel free to print embed share or hotlink this image and don t forget to credit us. All within a similar form. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.

Raspberry pi gpio pinout. Every pi model since the raspberry pi b has had 40 gpio pins though on the pi zero and zero. And faster interfaces is a strong competitor for the raspberry pi. Pins 1 2 39 40 are also labeled below j8 pinout 40 pin header the diagram below illustrates the gpio pinout using the pi4j wiringpi gpio numbering scheme.

Newer computers and game consoles have replaced the old machines where most of us learned to program. The raspberry pi 4 model b pi4b is the first of a new generation of raspberry pi computers supporting more ram and with siginficantly enhanced cpu gpu and i o performance. Gpio pinout rasp pi 1 model b rasp pi 2 model b. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.

Rev 1 pi alternate bcm numbers for the original 26 pin model a and b pi. Last modified by christopher stanton on oct 23 2019 4 29 am. Gpio pinout rasp pi 1 rev1 and rev2. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.

This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. We ve whipped up a simple graphical raspberry pi gpio pinout. One of the most significant changes to the raspberry pi model b is the 40 pin header j8. Raspberry pi gpio layout model b.

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.
