TEA5767 Stereo FM Radio Module with Detachable Antenna

TEA5767 Stereo FM Radio Module with Detachable Antenna is a highly integrated digital tuning solution designed for modern electronics enthusiasts and engineers. This versatile TEA5767 FM Radio Module utilizes a single-chip electronically tuned FM stereo radio, which perfectly simplifies the design of high-quality receivers. Consequently, it enables seamless integration into microcontroller projects like Arduino and ESP32. Technician’s Note: While the module provides a 3.5mm jack, this is a **Line-Level output**; therefore, you must use an external amplifier to drive 4-Ohm or 8-Ohm speakers. The inclusion of a detachable telescopic antenna significantly improves signal acquisition while offering flexibility for custom enclosure mounting. Furthermore, this module is 5V logic tolerant, making it directly compatible with the Arduino Uno without needing level shifters. Indeed, the digital PLL synthesizer ensures stable frequency selection across the entire FM band. Briefly, it delivers a professional-grade radio experience for any hobbyist development kit.

Key Features:

• High-Precision PLL Tuning: Featuring a Phase-Locked Loop (PLL) synthesizer, the module locks onto frequencies with zero drift, consequently ensuring clear reception of distant stations.
• Dual Signal Processing: Built-in Stereo Noise Cancelling (SNC) and High-Cut Control (HCC) algorithms work together to reduce background hiss in weak signal areas.
• Detachable RF Antenna: The gold-plated RF connector supports the included telescopic antenna, therefore allowing users to swap for high-gain external antennas if required.
• Low Power Consumption: Drawing only 15mA during active operation, it is ideal for battery-powered portable radio projects and wearable electronics.
• Standard I2C Interface: The 2-wire serial bus allows for easy control of frequency, muting, and signal strength monitoring through simple software commands.
