Product Description
2pcs 433MHz TTL Interface 100mW Industrial RF module SV612+2pcsRubber antenna + 1pcs USB bridge board

SV612 is highly integrated, multi-channels 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. SV612 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 SV612 wildly deployed in many fields and applications.
