We already offered this kit a long time ago. And now it made it back to our catalogue. The kit is very easy to build just by matching the parts in the bag with the print on the PCB.

The FM Spy Microphone and FM Transmitter DIY Soldering Kit has an on-board microphone, which makes it a wireless FM microphone or “bug”. Additionally, an external audio source can be connected (3.5mm jack).

The modulation frequency can be adjusted in a wide range of about 76 to 110MHz, covering the entire FM radio band.

The modulated output signal can be received with every FM receiver like the one in your car, at home or even on your phone.

A wire serves as the antenna but can be replaced with any other antenna made for that frequency range (like a telescopic antenna, for example).

  • Operating voltage: 3-6V
  • Current consumption: <50mA
