Pi-FM-RDS is a C program that turns a Raspberry Pi into an FM radio transmitter, generating FM modulation with real-time RDS (Radio Data System) data such as station name and radiotext. It uses the Pi's PWM generator via DMA to emit VHF signals on GPIO 4 and supports monophonic or stereophonic audio from WAV files.
Use cases
- transmit an FM radio signal from a Raspberry Pi
- broadcast RDS station name and radiotext data
- experiment with FM stereo audio transmission
- send audio from a WAV file over an FM carrier
- learn how FM/RDS modulation works with cheap hardware
When to choose
- you own a Raspberry Pi (models 1-4, Zero, Zero 2) and want to experiment with FM/RDS transmission
- you need a software-defined FM transmitter without extra RF hardware
- you want to test RDS-enabled receivers with custom PS/RT/PI data
When to avoid
- you need a legal, licensed broadcast solution - unlicensed FM transmission is illegal in most jurisdictions
- you want a media center or a way to stream music to your stereo
- you need a production-grade transmitter with proper RF filtering and range
