2015年9月11日 · Are you out of luck? You would be, if you didn't have this ultra-cool TCA9548A 1-to-8 I2C multiplexer!

The TCA9548A is an 8-channel, bidirectional translating switch for I2C buses that supports Standard-Mode (100 kHz) and Fast-Mode (400 kHz) operation. The TCA9548A features I2C control using a single 8-bit control register in which each bit controls the enabling and disabling of one of the corresponding 8 switch channels for I2C data flow.

In this guide, you’ll learn how to expand the I2C bus ports (ESP32, ESP8266, Arduino) using the TCA9458A 1-to-8 I2C Multiplexer. This piece of hardware is useful if you want to control multiple I2C devices with the same I2C address. For example, multiple OLED displays, or multiple sensors like the BME280.
