• •Introducing：
• •The I2C communication protocol allows you to communicate with multiple I2C devices on the same I2C bus as long as all devices have a unique I2C address. However, it will not work if you want to connect multiple I2C devices with the same address.
• •I2C multiplexer allows you to communicate with up to 8 I2C devices with the same I2C bus. The multiplexer communicates with a microcontroller using the I2C communication protocol. Then, you can select which I2C bus on the multiplexer you want to address.
• •To address a specific port, you just need to send a single byte to the multiplexer with the desired output port number.
• •Package includes：
• •5 x TCA9548A I2C IIC Multiplexer Breakout Board
