Introduction

Heads up! This tutorial was written for Si4703 FM Tuner Evaluation Board V13 (WRL-12938). The 3.3V and GND pins are switched in the new revision. Make sure you connect to the correct pins for power if you are using an older version like V11 (WRL-10663) or the breakout board.

The Si4703 FM tuner evaluation breakout board enables you to tune in to FM radio stations, using the Si4703 FM tuner chip from Silicon Laboratories. This IC also works well for filter and carrier detection, and enables data such as the station ID and song name to be displayed to the user.
