Raspberry Pi 3 B Gpio

If you love pinout please help me fund new features and improvements.

Raspberry pi 3 b gpio. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. The relay switch is utilized by means of a low voltage pulse. 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. We have included all three iterations of the pi for the pinout diagram.

Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins. The raspberry pi gpio pinout guide. See below for the raspberry pi gpio pinout diagram.

The raspberry pi 3 model b raspberry pi 3 model b plus is the latest version of the raspberry pi a tiny credit card size computer. By the looks of the schematic the gpio pins are connected to 5v rail. Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats. 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.

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. For this purpose relays can be used on the raspberry pi. Often you want to control modules with a higher voltage with the raspberry pi. Electrical specifications of gpio.

Since the pi only tolerates a maximum of 5v the gpios even only 3 3v without relays there is the. The earlier models such as the raspberry pi b have just 26 pins. By studying the schematic you come to realise there are 3 more voltages 4 in total used on the pi. The original pi has an on board linear regulator which was limited to 50ma but the b and later have a switch mode regulator which can supply more.

Just add a keyboard mouse display power supply micro sd card with installed linux distribution and you ll have a fully fledged computer that can run applications from word processors and spreadsheets to games. This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces. Id sd id sc pins. But the pi 3 did get an upgrade in terms of usb power supply so more power hungry usb devices could be used without a powered hub.

3 3v 5v interfacing. See our other page here. If you re an owner of a raspberry pi b 2 zero or 3 then you will have 40 pins in total. In the pi zero and zero w the 40 gpio pins are unpopulated having the through holes exposed for soldering instead.

In this sub section the 5v supplied from the usb connector is filtered to give a nice stable 5v supply to the 5v0 rail. Raspberry pi 1 models a and b have only the first 26 pins. This means that you can t use the pwm output and play audio through the 3 5mm jack at the same time.
