SR652-Wireless Transceiver 3KM RF Medium Power Network Node Module
SR652 is highly integrated, medium power network node module. It adopts high performance Silicon Lab Si4432 RF chip. Si4432 has low reception sensitivity and 500mW output power to ensure longer RF range and high link quality. SR652 supports multiple channels and Net ID to enhance the anti-interfere ability. Users can configure the parameters through PC or in circuit. The features of small packet, long distance, wide working voltage and setting in circuit make SR652 wildly deployed in many fields and applications.

Antenna: It is an important part of communication system. Its performance directly affect the indicators of communication system.This module SR652 requires the antenna impedance as 50 ohm. To make the module in the best working status, we recommend that users use our company's antenna!
USB Bridge Board: Modules need to match relevant parameter,transmit data...etc, with PC.(you can choose configuration mode by wire jumper).
