## Description

Features: A way to get up to 8 same-address I2C devices hooked up to one microcontroller.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.Specifications:Material: electronic elementColor: black & purpleSize: 31*21.5*2.5mmPackage Included:1 x TCA9548 TCA9548A BoardNotes:Due to the difference between different monitors, the picture may not reflect the actual color of the item.
