Raspberry Pi 3 B Gpio Pins

The b offers 9 extra gpio pins which can be configured as inputs of outputs.

Raspberry pi 3 b gpio pins. If you re using the raspberry pi b 2 zero 3 or the latest raspberry pi 4 model b you ll discover that your board have a total of 40 gpio pins. Here is a diagram showing all 40 pins. 24x gpio pins. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w.

The raspberry pi gpio pinout guide. See below for the raspberry pi gpio pinout diagram. The extended header offers an additional 3 ground pins. This means that you can t use the pwm output and play audio through the 3 5mm jack at the same time.

Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. The earlier models such as the raspberry pi b have just 26 pins. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. Raspberry pi 2 3 pin mappings.

This brings the total number to 26 17 9. The raspberry pi model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. 2x 3 3v. If you love pinout please help me fund new features and improvements.

So that s a total of 8. The raspberry pi 3b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins. This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces.

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. If you re an owner of a raspberry pi b 2 zero or 3 then you will have 40 pins in total. Gpio a powerful feature of the raspberry pi is the row of gpio general purpose input output pins along the top edge of the board. 1x serial uarts rpi3 only includes mini uart 2x spi bus.

The pwm pin available on the gpio header is shared with the audio system true for model b so presumably true for model b not confirmed as full schematic not yet available. 5 minutes to read. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. We have included all three iterations of the pi for the pinout diagram.
