Programmable FM Radio Module

The TEA5767 Programmable FM Radio Module is a powerful single-chip FM radio receiver that brings full-featured radio capability to your DIY electronics projects with minimal effort and components. Built around the TEA5767HN IC from NXP/Philips, this module is designed for low-voltage applications, making it especially well-suited for 3.3V microcontroller platforms like Arduino, ESP32, ESP8266, Raspberry Pi, and STM32.

The module supports a wide frequency range of 76 MHz to 108 MHz, covering FM bands used worldwide — including United States, Europe, Japan, and India. This makes it usable for receiving local FM broadcasts virtually anywhere. The integrated Phase-Locked Loop (PLL) synthesizer provides precise, drift-free tuning, and the automatic gain control (RF AGC) ensures optimal performance across both weak and strong signal conditions.

The chip includes a complete FM signal chain: low-noise input amplifier, mixer, intermediate frequency selectivity, FM demodulator, and stereo decoder — all in a single package. This means you can build a fully functional stereo FM radio with just a few external components like an antenna wire and an audio amplifier. The soft mute and standby mode features add quality-of-life improvements such as silencing inter-station noise and reducing power consumption when the radio is idle.

Communication is handled via the I²C bus (SDA / SCL), making it incredibly easy to control from any microcontroller using just two wires. With popular open-source libraries available for Arduino and other platforms, you can write a working FM radio sketch in just a few minutes — including features like scanning, station memory, stereo control, and search functions.

Whether you are building a portable DIY FM radio, a smart car audio system, an MP3 player with built-in radio, an Arduino-controlled tuner, an emergency radio receiver, or a microcontroller-based audio project, the TEA5767 module provides a professional-grade FM radio solution in an incredibly small footprint.
