8pcs RDA1846S radio transmission system walkie talkie module SA818 VHF band 134 -- 174MHz with Scan function
SA818 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 SA808.SA818 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 SA818: SA818-U and SA818-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:
SA818-U: U band, 400 -- 480MHz,
SA818-V: V band , 134 -- 174MHz
