## What is I2C?

I2C (Inter-Integrated Circuit) is a two wire communication protocol that is used to read and write data to  peripherals devices form one master system (In our case the Jetson Module). It is commonly used in embedded hardware due to its simplicity & low power communication between components.&#x20;

This protocol is used on our hardware for several devices such as:

* Camera sensors
* Temperature sensors
* IMU's
* GPIO Port extender&#x20;
* and so on...
