Adafruit TCA9548A I2C Multiplexer

The TCA9548A 1-to-8 I2C multiplexer effortlessly manages multiple I2C devices with the same address on a single microcontroller. This dynamic gatekeeper navigates commands seamlessly, enabling up to 8 identical I2C devices to communicate effectively through one controller.

Featuring an adjustable base address range from 0x70 to 0x77, this multiplexer allows for straightforward integration. Simply write a single byte to the desired multiplexed output number, directing subsequent I2C packets to the correct port.

Designed for versatility, the multiplexer is compatible with both 3V and 5V logic levels. Connectors are suitable for use on breadboards with included pullup and pulldown resistors, simplifying the setup process.
