This breakout for the Silicon Laboratories Si4703 FM tuner chip is a little more stripped down than our FM Tuner Evaluation Board. If your project already has an amp and just needs a full-featured FM tuner, this is the board for you. Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.
