Description:
A personal FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player) to a standard FM radio. Most of these transmitters plug into the device's headphone jack and then broadcast the signal over an FM broadcast band frequency.
This module could modulate your voice on the FM radio wave. And anyone who has a radio device could receive it. We build everything on this module, which makes it very easy to create a tiny radio station. We also reate library for Arduino to work with this module.
The audio input signal amplitude adjustment and microphone sensitivity adjustment.
To connect FM module to microcontroller module, do:
GND ------------ GND
5V ------------ VCC
SDA ------------ SDA
SCL ----- ------- SCL
