Raspberry Pi 3 B Gpio Pinout
Newer computers and game consoles have replaced the old machines where most of us learned to program.
Raspberry pi 3 b gpio pinout. Raspberry pi 3 pinout click the image to enlarge it raspberry pi 3 is a development board in pi series. 1x serial uarts rpi3 only includes mini uart 2x spi bus. 2x 5v power pins. 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.
Raspberry pi 2 3 pin mappings. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. The 3v3 supply pin on the early raspberry pi had a maximum available current of about 50 ma.
Raspberry pi 3 model b. 24x gpio pins. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi.
Enough to power a couple of leds or a microprocessor but not much more. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. It can be considered as a single board computer that works on linux operating system.
The board not only has tons of features it also has terrific processing speed making it suitable for advanced applications. 2x 3 3v. Raspberry pi b gpio header details and pinout 14. 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.
What each pin does on pi 4 earlier models. Raspberry pi gpio pinout. By les pounder 16 june 2020. It also includes dozens of pinouts for raspberry pi add on boards hats and phats.
Explaining the raspberry pi gpio pinout ref. Raspberry pi gpio layout model b. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. 5 minutes to read.
On the raspberry pi model 3b the hardware based serial uart device dev ttyama0 has been re purposed to communicate with the the built in bluetooth modem and is no longer mapped to the serial rx tx pins on the gpio header. All raspberry pi since the model b can provide quite a bit more up to 500ma to remain on the safe side thanks to a switching regulator. Instead a new serial port dev ttys0 has been provided which is implemented with a software based uart miniuart. The comprehensive gpio pinout guide for the raspberry pi.
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. Every pi model since the raspberry pi b has had 40 gpio pins though on the pi zero and zero.
