Frequently asked questions

Can this module receive MP3 signals?
No, this module is designed to receive FM stereo signals. For MP3, use another specific module.

Which Arduino can I use?
Any Arduino or compatible with compatible pins.

Can I use a different power supply than 3.3V?
Check the datasheet for power supply specifications.

How long does the audio reception last?
The duration depends on the quality of the antenna and the FM station.
