Meet the Production-Ready Arduino Compatible HQ record and Playback Audio Module! With ease, you can record and playback up to eight sound bytes using your own voice, or PC.

Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386.

Ever wanted to build an FM radio? Armed with an Arduino and a RDA5807M FM radio module, T. K. Hareendran shows us how to get started.

We peeked at the schematic and the shield is more for letting the Arduino control the radio by changing the oscillator frequency rather than performing the SDR functions.
