Here are the key features and components of the TEA5767 FM stereo radio module:

FM Radio Reception: The TEA5767 module is designed to receive FM radio signals in the frequency range of 76 MHz to 108 MHz, which is the standard FM radio broadcast band in many countries.

Stereo Audio Output: This module is capable of providing stereo audio output, allowing you to listen to FM radio broadcasts in stereo when connected to appropriate speakers or headphones.

Digital Tuning: The TEA5767 module uses digital tuning to select and lock onto specific FM radio frequencies. This provides precise tuning control and minimizes drift.

Automatic Frequency Control (AFC): The module typically includes AFC functionality to automatically adjust the frequency and reduce drift when the signal is weak or unstable.

I2C Interface: The module communicates with a microcontroller or other host device through an I2C (Inter-Integrated Circuit) interface. This allows for easy control of tuning and other settings.

Antenna Connection: The module often includes an antenna connection point where you can connect an external antenna to improve signal reception. The "Free Cable Antenna" likely refers to an included antenna or a separate cable antenna you can use.

Power Supply: The module requires a DC power supply voltage within its specified operating range, which is usually around 2.5V to 5.0V, depending on the specific version.

Audio Output: The module provides audio output pins that can be connected to speakers or headphones for audio playback.
