Connect them to the SparkX PCA9846 Qwiic Mux to get them all talking on the same bus! This Qwiic Mux enables communication with multiple I\u003csup\u003e2\u003c\/sup\u003eC devices that have the same address. This Qwiic Mux also has eight configurable addresses of its own, allowing for up to 32 I\u003csup\u003e2\u003c\/sup\u003eC buses on a single connection. To make it even easier to use this multiplexer, all communication is enacted exclusively via I\u003csup\u003e2\u003c\/sup\u003eC, utilizing our handy Qwiic system.\u003c\/p\u003e \u003cp\u003eThe PCA9846 Qwiic Mux is very similar to our classic \u003ca href=\"https:\/\/www.sparkfun.com\/products\/16784\"\u003e8-channel Qwiic Mux\u003c\/a\u003e, except:\u003c\/p\u003e \u003cul\u003e \u003cli\u003eIt has four multiplexed Qwiic ports, plus Qwiic Main In and Out connections, on a super-cute 1\" x 1\" PCB\u003c\/li\u003e \u003cli\u003eThe PCA9846 has a \"Who Am I\" (Device ID) product identification register which makes it \u003cem\u003emuch\u003c\/em\u003e easier to detect in auto-detect DataLogger \/ OpenLog applications.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eWe've written a dedicated \u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_PCA9846_Mux_Arduino_Library\"\u003eArduino Library\u003c\/a\u003e for the PCA9846 to get you up and running as qwiicly as possible!\u003c\/p\u003e \u003chr\u003e \u003cp\u003e\u003cem\u003eThe \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003eSparkFun Qwiic Connect System\u003c\/a\u003e is an ecosystem of I\u003csup\u003e2\u003c\/sup\u003eC 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.
