Adafruit 4 Channel Qwiic I2C Multiplexer - PCA9546A
Introducing the Adafruit 4 Channel Qwiic I2C Multiplexer - PCA9546. It resolves the issue of connecting multiple I2C sensors with fixed addresses to a microcontroller. Features adjustable I2C addresses, accommodating up to four same-address I2C devices. Utilizing the PCA9546, it integrates seamlessly with one microcontroller. Operating it is straightforward, set at I2C address 0x70, adjustable from 0x70 to 0x77 using jumpers. Includes five JST SH 1mm connectors and an onboard 3.3V 500mA regulator for seamless integration with 5V microcontrollers. Adjust power and logic level to 3V with ease. Complete with mounting holes for easy system integration.
