I2C
I2C (Inter-Integrated Circuit) is a serial communication protocol for connecting multiple devices.
Definition
I2C uses two wires: SDA (data) and SCL (clock) to create a bus where multiple devices can communicate. Each device has a unique address. Operates at standard Voltage levels (3.3V or 5V).
Key Points
- Two-wire interface (SDA, SCL)
- Multiple devices on same bus
- Slower than SPI but simpler
- Common in sensors and displays
