TEA5767 FM Stereo Radio Module

The TEA5767 is a single-chip, electronically tuned FM stereo radio module designed for low-voltage applications and easy integration with microcontrollers. Built around the Philips/NXP TEA5767HN IC, it integrates the complete FM front-end, intermediate frequency (IF) selection, and demodulation, requiring only a minimal number of external components. The module receives FM broadcasts across the 76MHz to 108MHz band and is controlled entirely over an I2C bus, making it directly compatible with Arduino, STM32, and ESP32 boards without manual tuning. A low-noise RF input amplifier and automatic gain control (AGC) provide high sensitivity, while the onboard stereo decoder delivers clear left and right audio channels through a standard 3.5mm jack. The module also supports automatic frequency search, standby mode, and software-controlled mono/stereo switching and high-cut filtering, all accessible over the bus. With compact dimensions of 51mm × 15mm × 5mm, this TEA5767 FM radio module fits easily into portable audio players, smart home devices, MP3 players, and DIY receiver projects. Whether the goal is to add radio functionality to an existing microcontroller project or to build a standalone FM stereo receiver module, this board provides a reliable, well-documented I2C FM radio module solution.

Application

1. Portable audio players, MP3 players, and smart home devices requiring an FM radio source.
2. Arduino, STM32, and ESP32 projects that need an I2C-controlled FM receiver.
3. DIY Bluetooth speaker builds and compact audio systems with auxiliary radio functionality.
4. Educational demonstrations and prototyping of FM reception and I2C communication.
5. Small-scale production of custom radio receivers where a pre-assembled FM module reduces development time.
