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.
You will need the following materials to work on this project.
Keep in mind you will also need standard soldering materials to complete this tutorial, as well as either a set of speakers or headphones with a 3.5mm jack to plug into the Si4703 board.
If you aren't familiar with any of the concepts below, check out these links and get caught up before moving ahead with the Si4703.
Asynchronous serial communication concepts: packets, signal levels, baud rates, UARTs and more!
Installing an Arduino Library
How do I install a custom Arduino library? It's easy! This tutorial will go over how to install an Arduino library using the Arduino Library Manager. For libraries not linked with the Arduino IDE, we will also go over manually installing an Arduino library.
