I2C/I3C

Last updated May 16, 2025, generated by Sumble

What is I2C/I3C?

I2C (Inter-Integrated Circuit) is a serial communication protocol primarily used for short-distance, on-board communication. It uses two wires, SDA (Serial Data) and SCL (Serial Clock), to allow multiple devices to communicate with a master device. It is commonly used for connecting microcontrollers to peripherals like sensors, EEPROMs, and displays.
