2pcs UHF Walkie Talkie Module SA818S-CE (SA818S is pin to pin compatible with SA818)
If you need VHF(134 ~ 174 MHz) frequency, just leave message please.
SA818S is a low cost but high performance integrated walkie talkie module.With built-in high performance microcontroller, narrow band rf transceiver and standard UART interface it can be easily used and succeed all the walkie talkie function with good quality voice and long distance transmission. Users only need to connect external audio amplifiers, microphone or speaker with this module ,then it can work as a small walkie talkie with 1W output . In open area, it can easily achieve 3.5-5Km communication. Simplified interface and ultra small size make this module a wide range of applications, also can conveniently embed into various handheld devices,to improve the comprehensive performance of end products.
