## Overview

The Adafruit TCA9548A I2C Multiplexer is a powerful tool that allows you to connect up to 8 identical I2C devices to a single microcontroller. With its adjustable I2C address and user-friendly design, this multiplexer is perfect for expanding your I2C network while maintaining compatibility with both 3V and 5V systems.

## Description

Adafruit TCA9548A I2C Multiplexer

## Features

- Finally, a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command.
- Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77) and you simply write a single byte with the desired multiplexed output number to that port, and bam - any future I2C packets will get sent to that port. In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part.
- Like all Adafruit breakouts, we put this nice chip on a breakout for you so you can use it on a breadboard with capacitors, and pullups and pulldowns to make usage a snap. Some header is required and once soldered in you can plug it into a solderless-breadboard. The chip itself is 3V and 5V compliant so you can use it with any logic level.

## Questions & Answers

**Q: Could this be used to create multiple analog inputs? More specifically for an esp 8266.**
A: This item is for multiple I2C... it is for digital sensors and LCDs. You would need a analog multiplexer... not this one.
