Another “spy bug” from our catalog of easy DIY electronic kits. This wireless microphone transmitter send on an adjustable frequency of 88-108MHz FM, and can be received with every standard FM radio like car stereo etc.
This kit is pretty easy to build, although we recommend to follow the instructions shown in the picture gallery.
Every part is clearly printed on the circuit board, and there is no additional tutorial needed to successfully assemble it (necessary knowledge of building electronic circuits and about electronic components provided).
This module needs a power supply 3-6V, and max. 15mA continuous current.
The transmission range can be less than 10m (in buildings) to about 50m (free air), depending on environmental conditions.
We have a tiny pocket FM radio DIY kit in our catalog, which works well together with the wireless FM microphone transmitter.
PCB size is 54 x 41mm
