⭐ Detailed Description
This TCA9548A multiplexer module is designed to expand the number of I2C devices that can be connected to a single microcontroller. When multiple sensors or modules share the same I2C address, they cannot be used on the same bus. The TCA9548A solves this by providing 8 selectable downstream channels, each isolated from the others.
The module communicates through a standard I2C interface and supports multiple address configurations via the A0–A2 pins. It is widely used in robotics, environmental monitoring, multi‑sensor arrays, and advanced development projects.
Its compact PCB design and clear pin labeling make it easy to integrate into both beginner and professional applications.
