It is an integrated radio FM station on a chip, so the users 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.
I2C interface 5V TTL compatible
for Arduino plug and play
Onboard MIC
VCC Input: 3.0V ~ 5.0V
Audio entrance signal regulating of amplitude and microphone regulating of sensitivity.
Wireless FM audio microphone stereo-transmission FM radio small power.
Antenna port on the board,Any metal line about 75cm can serves as an antenna.
Ever thinking about set up a music radio station yourself? I think it would be great if you could build a music station and share your music with others. Pretty cool, right? This module could modulate your voice on the FM radio wave(70-108 MHz). And anyone who has a radio device could receive it.
Connect Arduino with FM Module as below :
GND connect with GND
5V connect with VCC
SDA connect with SDA
SCL connect with SCL
Then connect the antenna
Any metal line about 75cm can serves as an antenna
