Embedded Walkie Talkie Module LS-818 RDA1846S Chip UHF 400 - 480 MHz RDA1846S Chip 5km

I am pleased with them. It was a good choice for our small application. It is a robust device even it has a cheap price. I will use them in our further applications when we should use remote control. Thank you for your support.

Great news! We successfully performed the installation of the two units and transmitted our 4-20mA signal with both antennae. Even the smaller antenna suffices to transmit the signal without any losses whatsoever. So you can understand that we are very happy :) .

I believe you and your products. Sunny is very responsible. The RF modules are really strong and stable. Engineer's suggestions are useful to me. The most important is module's program can updrade on-line by myself. For some special projects, they can customize according my requirements. Thank you for your support all the time.

—— Singh from India

First of all I'd like to thank you for you're prompt service. The system now works perfectly. I left a positive response on your web site. I hope it attracts more customers for you.

wireless audio transceiver module

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
