SoundBytes Cicada



The SoundBytes Cicada is a simple, fully self-contained sound module that plays a realistic scissor-grinder cicada song.  With this sound module, the more the merrier!  Place several units together or spread out around the layout.


  • Scissor-grinder cicada song sampled from actual audio
  • Every unit is unique!
  • Use several units together to create a realistic "chorus"
  • Integrated speaker & volume control
  • Easy to install and use
  • Ideal for adding ambient sound to timber or river scenes
  • Powered from 5V to 24V

Electrical Connections

The SoundBytes module needs 5-24 volts of clean direct current (DC) power to operate.  Connect the white wire to GND to activate the sound.  Leave the white wire disconnected to turn the sound off.

Red Wire = 5V to 24V
Black Wire = GND
White Wire = GND to activate (Do not exceed 3.3V on the white wire!)
