Mux Breakout - 8 Channel TCA9548A (SparkFun Qwiic )

Mux Breakout - 8 Channel TCA9548A (SparkFun Qwiic )

The SparkFun Qwiic Mux Breakout conquers a common I2C roadblock: conflicting device addresses. This multiplexer acts as a bridge, allowing up to 8 I2C devices with identical addresses to coexist on a single bus. With 8 configurable addresses, it effectively creates virtual I2C lanes for each device. Universally compatible with both I2C and SMBus protocols, it integrates seamlessly with a wide range of sensors and I2C modules. The Qwiic Mux also offers voltage translation for different power levels and hot-swapping for convenient device insertion/removal, making it a powerful tool for complex sensor networks or projects requiring expanded I2C connectivity.
