From the project

Part of the Teknotrek YouTube channel, this repository includes KiCad files for an FM Radio project using Arduino Nano, Si4703, and other components. Check out our YouTube channel for tutorials and build videos https://www.youtube.com/channel/UCLOmh3PNItDSgDy55UoxpgQ

This project is an FM radio built using the Arduino Nano, Si4703 FM module, PAM8403 stereo amplifier module, rotary encoder, and a 16x02 LCD display. It is designed to tune FM frequencies and provide stereo audio output through speakers.

- Arduino Nano: Used as the microcontroller. - Si4703 FM Radio Module: Receives FM radio signals. - PAM8403 Stereo Amplifier Module: Amplifies the audio output. - Rotary Encoder: Used for tuning the frequency and adjusting the volume. - 16x02 LCD Display: Displays the current FM frequency.
