Description
The CJMCU TCA9548A I2C Multiplexer Module allows you to connect up to 8 I2C devices with the same address to a single microcontroller using only one I2C bus. This is especially useful when working with multiple identical sensors or devices that can’t have their I2C address changed. Controlled via standard I2C protocol, the onboard TCA9548A chip lets you selectively enable one or more channels for communication, making it a powerful tool for complex projects.
Features:
8-Channel I2C Expansion: Connect up to 8 I2C devices with the same or different addresses.
TCA9548A Chip: High-performance I2C switch/multiplexer from Texas Instruments.
Individual Channel Control: Select channels independently or in combination via I2C commands.
