Do you have too many sensors with the same I²C address? Connect them to the SparkX PCA9846 Qwiic Mux to get them all talking on the same bus! This Qwiic Mux enables communication with multiple I²C devices that have the same address. This Qwiic Mux also has eight configurable addresses of its own, allowing for up to 32 I²C buses on a single connection. To make it even easier to use this multiplexer, all communication is enacted exclusively via I²C, utilizing our handy Qwiic system.

The PCA9846 Qwiic Mux is very similar to our classic 8-channel Qwiic Mux, except:

It has four multiplexed Qwiic ports, plus Qwiic Main In and Out connections, on a super-cute 1" x 1" PCB
The PCA9846 has a "Who Am I" (Device ID) product identification register which makes it much easier to detect in auto-detect DataLogger / OpenLog applications.

We've written a dedicated Arduino Library for the PCA9846 to get you up and running as qwiicly as possible!

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. 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.
