## Description



## Features

- Do you have too many sensors with the same I2C address Put them on the SparkFun Qwiic Mux Breakout to get them all talking on the same bus!
- The Qwiic Mux also has eight configurable addresses of its own, allowing for up to 64 I2C buses on a connection. Also allows you to change the last three bits of the address byte, allowing for eight jumper selectable addresses if you happen to need to put more than one Qwiic Mux Breakout on the same I2C port.
- All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
- Operating Voltage: 1.65V - 5.5V. Operating Temperature: -40 - 85 C. I2C Address: 0x70 (default) up to 0x77.
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
