Raspberry Pi 3 B Pin Diagram Explanation

It can be considered as a single board computer that works on linux operating system.

Raspberry pi 3 b pin diagram explanation. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. Wiringpi for gordon henderson s wiring pi library. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program. Now let s get started on this raspberry pi gpio tutorial we will be taking a look at the different types of pins that available how to enable the modules what a breakout kit is and finally build a very simple circuit.

In the pi zero and zero w the 40 gpio pins are unpopulated having the through holes exposed for soldering instead. Raspberry pi 1 models a and b have only the first 26 pins. A downside to bcm is they have changed between versions raspberry pi rev 1 vs raspberry pi rev 2 and made do in the future. Raspberry pi gpio tutorial.

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. For example on the raspberry pi 3 the pin below 3v3 is gpio2 so the number for this pin is 2 in bcm mode. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. 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.

This tutorial will. By johnny winter 25 jul 2014. Raspberry pi 1 models a and b pi 2 model b pi 3 models a b and b pi 4 and pi zero zero w and zero wh gpio j8 have a 40 pin pinout. In the diagram above you can find the number after gpio.

To prevent the voltage regulator for example mxl7704 r3 from malfunctioning do not use 3 3 volts on the raspberry pi gpio and instead use a 5 volt to 3 3 converter. These are the small numbers next to the header e g. Newer computers and game consoles have replaced the old machines where most of us learned to program. Available at the same price as its predecessor the b is the same but different.

Announced on 14th july 2014 the raspberry pi b is a revision to the hugely popular model b. The raspberry pi 3b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. Raspberry pi 3 is a development board in pi series. Pins 1 2 39 40 are also labeled below j8 pinout 40 pin header.

Physical or board correspond to the pin s physical location on the header. These are shown as a tooltip when you mouseover a pin. And 3 3 volts goes through the voltage regulator for example mxl7704 r3 which burns at the closing of 3 3 volts gnd. If you re an owner of a raspberry pi b 2 zero or 3 then you will have 40 pins in total.
