Raspberry Pi Pinout I2c

Find out what the pins do on the raspberry pi 4 header.

Raspberry pi pinout i2c. The raspberry pi has two i2c connections at gpio 2 and 3 sda and scl are for i2c0 master and physical pins 27 and 28 are i2c pins that enable the pi to talk to compatible hat hardware. Below you can view the pinout for the raspberry pi 2 and newer. The additional 24 pins were all introduced with the release of the. Raspberry pi 4 pinout.

I2c inter integrated circuit. L i2c del raspberry è un modo estremamente utile per comunicare con molti tipi diversi di periferiche esterne dall expander digitale mcp23017 ad un atmega collegato. 1x i2c bus. The raspberry pi s i2c pins are an extremely useful way to talk to many different types of external peripheral.

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 i2c pins include a fixed 1 8 kohms pull up resistor to 3 3v. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Wiring pi pin 9.

24x gpio pins. Raspberry pi pin i2c. Support pinout xyz on patreon. 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.

The first 26 pins on the raspberry pi 2 and newer are the same as the raspberry pi 1 revision 2. The comprehensive gpio pinout guide for the raspberry pi. Bcm pin 1 on rev 1 very early pi. Scl i2c clock is one of the i2c pins on the pi learn more about i2c.

This means they are not suitable for use as general purpose io where a pull up is not required. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. Raspberry pi 2 3 pin mappings. 1x serial uarts rpi3 only includes mini uart 2x spi bus.

From the mcp23017 digital io expander to a connected atmega. It also includes dozens of pinouts for raspberry pi add on boards hats and phats. Raspberry pi 2 3 and 4 pinout. 5 minutes to read.

Not only is the raspberry pi 4 bursting with new hardware features but under the hood there are some extra gpio functions to make life a bit easier allowing users to expand their peripherals to their projects without requiring additional hardware in particular there are a bunch of extra i2c uart and spi interfaces that can be used on the raspberry pi 4. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. 2x 5v power pins.
