TCA9548A 8-Channel I²C Multiplexer Module
The Robu Studio TCA9548A 8-Channel I²C Multiplexer Module allows an Arduino, ESP32, ESP8266, or compatible controller to communicate with multiple I²C devices that share the same address. It splits one I²C bus into eight independently selectable downstream channels, making it useful for complex sensor networks and multi-display projects. Ideal for school STEM laboratories, robotics competitions, IoT applications, and advanced electronics prototyping. Key Features: 8 independently selectable I²C channels Helps resolve I²C address conflicts Configurable I²C address, typically 0x70–0x77 Compatible with supported Arduino, ESP32, ESP8266, and Raspberry Pi projects Compact breakout-board design
