SI4703 FM Stereo Radio Module

SI4703 FM Stereo Radio Receiver Module

I2C Digital Programmable Low Power 76Mhz-108Mhz 3.5mm Audio Socket Audio Music Mobile RF Receiver

The product does not work on its own. Settings such as frequency selection must be made with a different board over IIC communication. If you do not have the knowledge to program such a board, do not purchase it.

      It is a radio module made with the SI4703 integrated circuit. It uses IIC communication. It receives FM broadcasts between 76/108Mhz. The need for peripheral components is very very low. All necessary complex circuits are placed inside the integrated circuit. There is very little component need and those come already added on the module.

     With I2C communication, a connection is quickly established with a kit such as arduino, frequency selection is made and other necessary settings can be made. It has a supply voltage between DC 2.5V / 5V ( preferably 3.3V ).  You can start using it by connecting an antenna and a speaker to the audio output.
