Raspberry pi 3 b wiring diagram. The comprehensive gpio pinout guide for the raspberry pi. Raspberry pi 3 model b. This section contains documentation with technical information about the raspberry pi hardware including official add ons and the pi itself. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program. Scl i2c clock is one of the i2c pins on the pi learn more about i2c. Raspberry pi 3 model b.
Raspberry pi 3 model a. Raspberry pi model b. Pir stands for passive infrared. Here we are using a pir motion sensor. It also includes dozens of pinouts for raspberry pi add on boards hats and phats. Next we need to connect the led to pin 3 on the raspberry pi gpio.
You can check out the connection diagram below to do that. To update or install on a raspbian lite system. 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. The following tables give the mapping of the raspberry pi gpio pins to the p1 gpio connector in relation to the pin numbers and the physical location on the connector. Support pinoutxyz on patreon. Wiringpi is developed and tested on a raspberry pi only.
Each pin on the raspberry pi is named based on its order 123 as shown in the diagram below. The raspberry pi 3b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. If you are trying to install it on anything else then good luck. It is for c and rtb basic programs on. This is a representation of the gpio connector as viewed looking at the board from above. Raspberry pi 2 model b.
Bcm pin 1 on rev 1 very early pi. Wiring pi gpio interface library for the raspberry pi. Wiring pi pin 9. Newer computers and game consoles have replaced the old machines where most of us learned to program. 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 pis gpio interfaces.
