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:
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.
