NEW GUIDE: Adafruit PCA9546 4-Channel STEMMA QT Multiplexer #AdafruitLearningSystem #Adafruit @adafruit @blitzcitydiy

The PCA9546 1-to-4 STEMMA QT I2C multiplexer lets you get up to 4 same-address I2C devices hooked up to one microcontroller – this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins connected with STEMMA QT cables.

The Adafruit PCA9546 4-Channel STEMMA QT Multiplexer guide has everything you need to get started with using the STEMMA QT I2C multiplexer breakout. There’s pages for overview, pinouts, CircuitPython, Arduino and download resources.
