FEATURES:
A popular FM stereo radio module for receiving FM radio broadcasts in electronics projects is the TEA5767. FM radio signals in the frequency range of 76 MHz to 108 MHz can be received by this module. It's a small and adaptable way to build standalone FM radios or include FM radio capabilities into your projects.
FM Radio Reception: The TEA5767 module is designed to receive FM radio signals within the 76 MHz to 108 MHz frequency range, which is the standard FM radio band used in many regions.
Stereo Audio Output: This module supports stereo audio output, enabling the reception of FM radio broadcasts in stereo when connected to suitable speakers or headphones.
Digital Tuning: The TEA5767 uses digital tuning to precisely select and lock onto specific FM frequencies, ensuring accurate control and minimal signal drift.
Automatic Frequency Control (AFC): The module includes AFC functionality, which automatically adjusts the frequency to maintain a stable connection and reduce drift, especially when the signal is weak or fluctuating.
I2C Interface: Communication with a microcontroller or host device is facilitated through the I2C interface, allowing easy control of tuning and other settings.
Antenna Connection: The module features an antenna connection point for attaching an external antenna, which can enhance signal reception. The "Free Cable Antenna" may refer to an included antenna or an optional cable antenna for improved reception.
Power Supply: The module requires a DC power supply in the range of 2.5V to 5.0V, depending on the version.
Audio Output: Audio output pins are available for connecting to speakers or headphones, enabling playback of FM radio broadcasts.
