FM Transmitter Module

Description:
FM Radio Transmitter Module is an FM band, wireless transmitter with high fidelity stereo signal, which is based on KT0803 and similar chip. This chip is an ultra low power consumption, automatic power down on input silence detecting and high grade performance upper than the amateur transmitter. It is an integrated radio FM station on a chip, so the designers can easily create their desired FM radio station, to share and transmit their speech, voices, musics, etc. It modulates audio or pulse on the FM radio wave and any devices with an FM receiver module could receive its signal. The FM transmitter module has an I2C interface and compatible with 5V TTL levels, which enable it easily to interface with microcontroller and other Arduino boards. It has an onboard microphone, without any antennas. You can use a 75 centimeter long of a typical wire as an antenna, directly connected to the module.
