SNR654 is highly integrated, RS232 port radio 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. SNR654 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 SNR654 wildly deployed in many fields and applications.
