the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the additional one is on pins 20 and 21.

The SI473X device can work from 1.6V to 3.6V. If you are not using a 3.3V Arduino board, that Arduino will send 5V signals to the SI473X device through the digital pins and the I2C bus. That configuration can make the system unstable or damage the Si473X device. To fix this, use...
Just to the right of the reset button are the ICSP pins. These allow you to communicate using the I2C protocol, which allows for much more complex kinds of communication than the other ports. You can also use analog pins 4 and 5 to communicate over I2C. In Chapter 8, we’ll be commun...

This module is designed to communicate using the I2C protocol. So, at first, find the SDA and SCL pin of your Arduino uno or compatible board. If you are using Arduino uno board pin A4 and A5 is SDA and SCL pin respectively. Similarly, if you are using Arduino mega pins 20 and 21 ...
