This FM Radio Transmitter is designed to modulate your sound files into FM radio broadcasting so that it can be listened to by anyone with the receiving device. It has I2C interface that is compatible with 5V TTL level. It also has a simple library file so that the user can design it easier.

The module is an FM transmitter that can be controlled by a microcontroller, with many functions.

The integrated circuit used can communicate via the I 2 C interface and can transmit stereo signal. As an antenna, you only need to tie a 50 - 75 cm wire.

This module can be useful for building your own FM modulator that you can control with an Arduino development pad. With this, you can turn off, turn on the modulator, or use silence detection.
