Description:
This module is based on the Si4713 chip. The Si4713 integrates the complete transmit functions for standards-compliant unlicensed FM broadcast stereo transmission. The chip also allows an integrated power scanning receiver to identify low signal power FM channels.
Users must comply with local regulations on radio frequency (RF) transmission. You can wire up to your favorite microcontroller to the I2C data lines to set the transmit frequency and play line-level audio into the stereo headphone jack.
This transmitter even has RDS/RBDS support, which is text/data transmissions that many modern FM receivers support.

Features:
Integrated receive power measurement 
Worldwide FM band support (76–۱۰۸ MHz) 
Requires only two external components 
Frequency synthesizer with integrated VCO 
Digital stereo modulator 
Programmable pre-emphasis 
Analog/digital audio interface 
Audio silence detector 
Programmable reference clock
RDS/RBDS encoder (Si4713 only)
PCB loop and stub antenna support with self-calibrated capacitor tuning 
Programmable transmit level 
Audio dynamic range control 
Advanced modulation control 
۲٫۷ to 5.5 V supply voltage 
Integrated LDO regulator 
Designed for compatibility with the cellular operation
