1. Product Outline

    The SR_FRS_0W5 (VHF)  is a low cost but high performance integrated walkit talkie module. With built-in high performance micro controller, narrow band rf transceiver and standard Uart interface,it can be easily used and succeed in 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 0.5W output . In open area, it can come to performance of 3Km communication. Simplified interface and ultra small size make this module into a wide range of applications, also can conveniently embed into various handheld devices,to improve the comprehensive performance of end products.

      Besides the  excellent voice intercom, The more important feature is this module has  the data/SMS transfer ability;  up to 60 byte can be sent at one time;  it  is compliance  with the standard UART transfer protocol;

The key feature is its ultra small size: 15*25*3.0MM, it is easy to be embed into other

 system such as mobile phone, MP3,MP4,etc
