What is the I2C often mentioned in the lamp?

1. I2C is a kind of bus and also a communication protocol. It has the advantages of fewer pins, simple hardware implementation, and strong scalability. Another advantage of the I2C bus is that it supports multiple masters. Any device on the bus that can send/receive data can occupy the bus. 2. Currently, our platform supports SM16726EB and SM2135E to communicate with our modules through the I2C protocol.
