LS-818 is a low cost and high performance integrated walkie talkie module. This module is the 2nd generation of the walkie talkie module and the upgraded version of LS-808.LS-818 comes with built-in high performance microcontroller, narrow band rf transceiver and standard UART interface. It is easy to use. Users only need to add external audio amplifier, microphone and speaker, then it becomes a professional walkie talkie with 1W output. In open area, it can easily achieve 3.5-5Km communication distance. Simplified interface and ultra small size make this module widely used in various applications and conveniently embedded into various handheld devices.

There are two frequency bands of LS-818: LS-818-U and LS-818-V. The only difference is the frequency range. The others are same, including module size, interface, software protocol, etc. The two modules’ frequency ranges are:
LS-818-U: U band, 400 --480MHz LS-818-V: V band, 134 -174MHz

Features:

  • Frequency: 400 ~ 480 MHz (UHF)
  • Tx and Rx frequency, Tx and Rx CTCSS can be set alone.
  • Band width 12.5/25KHz
  • Output power up to 1 w
  • Transmission distance up to 3.5 to 5 km in Open area
  • Sensitivity: - 124 DBM
  • High integration,small size
  • Built-in EEPROM, data kept even power off off
  • 38 level CTCSS code / decode
  • 166 level positive, reverse phase CDCSS digital audio
  • 8 level squelch
  • 8 adjustable volume
  • High/ low power is optional (500 mw) - 1 w
  • Wide range of working voltage 3.3 to 5.5 V with 1 ppm TCXO crystal, stable performance

Applications:

  • Small walkie talkie
