- FM Transmitter Module V2.0 Digital FM Radio Module for Arduino Microphone Audio
- This module could modulate your voice on the FM radio wave(70-108 MHz). And anyone who has a radio device could receive it.
- which makes it very easy to build a tiny radio station.
you could wire them in the following way :
