Adafruit PCA9546 4-Channel I2C Multiplexer

Connect up to four same-address I2C devices seamlessly with the PCA9546 1-to-4 I2C multiplexer. This versatile component manages multiple devices by channeling commands to selected I2C pins, overcoming the limitations of fixed-address sensors on your Arduino projects.

The multiplexer operates on an I2C address of 0x70, adjustable from 0x70 to 0x77, allowing flexible configurations. Simply write a single byte to the port for the desired output, enabling specific I2C packet routing. Scale your connectivity with the 8-channel TCA9548 option to control up to 32 identical-address devices.

Expertly designed for easy integration, it includes Adafruit's breakout with essential components like capacitors, pullups, and pulldowns for quick setup. Compatible with 3V and 5V logic levels, it fits various development environments. Please note that headers, cables, and sensors are sold separately. It’s just the PCB, ready for your innovative ideas!
