RDA5807M FM Stereo Radio Module RRD-102V2.0 76-108MHz I2C – Arduino

RDA5807M FM Stereo Radio Module (RRD-102V2.0) is a high-sensitivity, ultra-compact single-chip FM stereo radio module built around RDA Microelectronics’ RDA5807M (or RDA5802NM) chip. Measuring just 11×11.2mm, it integrates a complete FM receiver, digital frequency synthesizer, A/D converter, and audio output driver into a single low-cost module, requiring minimal external components and communicating via standard I2C interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers.

Key Features:

• RDA5807M single-chip FM receiver — minimal external components needed
• Ultra-compact 11×11.2mm form factor — fits any project size
• Worldwide FM band (76–108MHz) — compatible globally
• I2C interface — easy 2-wire connection to any microcontroller
• Built-in high-precision A/D and digital frequency synthesizer
• Built-in LDO regulator — wide voltage range (2.7–3.6V), low power consumption
• Built-in noise reduction circuit — clean, clear audio output
• Soft mute function — eliminates noise between stations
• Bass boost circuit — enhanced audio quality
• Direct 32Ω headphone output — no external audio amplifier needed
• External reference clock input support
• Drop-in replacement for 102BC module packages — no circuit redesign needed
• High sensitivity and strong anti-interference performance
