Raspberry Pi Gpio Pins Diagram

The raspberry pi 4 can be used in the external embedded system to communicate.

Raspberry pi gpio pins diagram. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. A powerful feature of the raspberry pi is the row of gpio general purpose input output pins along the top edge of the board. The raspberry pi model b features. More gpio more usb micro sd lower power consumption better audio neater form factor this higher spec variant increases the raspberry pi gpio pin count from 26 to 40 pins.

2x 3 3v. Now let s discuss pin layout. Here is the raspberry pi 4 default gpio pinout for the 40 pin j8 header. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board.

Gpio pins don t only perform the simple i o functions. In the diagram above you can find the number after gpio. We can use any of the gpio pins for our application. Support pinout xyz on patreon.

Raspberry pi 3 model b gpio pins. This is the configuration of the pins as you ll receive it when you first boot up raspbian or noobs with raspbian. We should define gpio pin which we want to use as an output or input. It also includes dozens of pinouts for raspberry pi add on boards hats and phats.

The header provides 5v on pin 2 and 3 3v on pin 1. To confuse things even more the gpio pins are sometimes renamed with another set of numbers. Raspberry pi 2 3 pin mappings. 1x i2c bus.

Gpio pins of raspberry pi 3 are shown in below figure. The raspberry pi has 40 gpio pins that connect to sensors lights motors and other devices. Here s a map and detailed explanation of what each does including on the pi 4. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.

2x 5v power pins. 24x gpio 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. 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 pi s gpio interfaces.

5 minutes to read. 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. For example on the raspberry pi 3 the pin below 3v3 is gpio2 so the number for this pin is 2 in bcm mode. Raspberry pi pins description.

There are now four usb 2 0 ports compared to two on the model b. The pins description is same for all models. It has a total of 40 pins from which 28 are gpio pins and the rest of them are power pins. 1x serial uarts rpi3 only includes mini uart 2x spi bus.

Some of the gpio pins are multiplexed with alternate functions like i2c spi uart etc.
