SR-FRS-1WU 400MHz-480MHz 1W UHF Analog walkie talkie module <h2>Product Outline</h2> <p><span> Product Outline</span> The SR_FRS_1W (UHF) 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 1W output . In open area, it can come to performance of 5Km 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 100 byte can be sent at one time; it is compliance with the standard UART
