hot sale 433/470/868/915 MHz wireless rf transceiver module TTL/RS232/RS485 sucker antenna usb converter board

Specifications

low cost, Small size, anti-interference,100mW, 1.4km distance, TTL /RS232/RS485 interface

SV611 is highly integrated, multi-ports radio data transceiver module. It adopts high performance Silicon Lab Si4432 RF chip. Si4432 has low reception sensitivity and 100mW output power to ensure longer RF range and high link quality. SV611 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 SV611 wildly deployed in many fields and applications.
