AJMRTC PCA9546 4Channel Qwiic I2C Multiplexer is a handy I2C bus expansion component kit built around PCA9546 integrated chip. It splits one I2C host port into four separate I2C channels, which perfectly resolves address conflict problems when deploying multiple I2C sensors with identical addresses in one circuit system. Fully compatible with Qwiic and STEMMA QT standard interfaces, this multiplexer supports quick plugin connection. Users can switch target communication channel through simple IO control logic, so different peripheral sensors can work orderly without hardware modification. Wellsuited for singleboard microcontroller projects, maker electronic experiments, multisensor acquisition systems and various DIY circuit development scenarios.
