FM FREQUENCY WIRELESS MICROPHONE MODULE DIY KIT

Frequency Range: 80MHz-108MHz
Operating voltage: DC3V-6V
TX antenna is connected: You can take a piece of wire as an antenna,
the antenna should not be too long, so as not to affect the frequency stability.

Debugging:
Connect the power and antenna test, the antenna can be used 20-40 cm thick wire
(antenna not too long, so as not to affect the frequency stability),
the package does not provide, you need to bring your own.
FM radio receiving equipment used to adjust the tightness
of the inductor coil on a simple wireless microphone,
so the radio signal received by the microphone.
