TCA9548A Pre-Soldered 1-to-8 I2C 8-Channel Multiplexer Module

TCA9548A 1-to-8 I2C 8-channel multiplexer module lets you expand a single I2C bus into eight selectable channels, making it easy to connect multiple sensors, displays, EEPROMs, or other peripherals while isolating traffic between devices. Built around the TCA9548A chip, it is ideal for resolving I2C address conflicts and managing complex multi-device setups in Arduino, Raspberry Pi, ESP32, and other microcontroller or SBC projects. This I2C multiplexer module is a practical choice for robotics, home automation, test fixtures, and general electronics prototyping where reliable I2C bus routing is needed. The header pins ship pre-soldered, so it works out of the box with no soldering required.
