Description & Details

Summary

  • The transmission frequency of the audio transmitter module can be adjusted, and the adjustable range covers 88‑108mhz national standard FM band.
  • The green component is a tunable capacitor, changing the tunable capacitor can change the transmit frequency.
  • With 0.7V‑9V wide voltage working range, long transmission distance, strong practicability.
  • You can use radios and mobile phones as receivers (the earphone cable for mobile phones makes the antenna sensitivity very poor and is not recommended).
  • Widely used in sound transmission pickups, audio microphones, sleep monitoring and other situations where sound needs to be captured.
