Product Description

 

2pcs/pack  SNR651 868MHz RS485 Interface Embedded  Multi-ports Network Node Module for Wireless Networking Data Transmission

 

SNR651 is highly-integrated RF module, which adopts high performance Si4432 from Silicon Labs. It has 3 optional Interface (TTL, 232, 485). SNR651 has high sensitivity and 500mW output power to achieve long RF range and reliable RF communication. SNR651 comes with many parameters which are configurable, such as:  frequency, data rate, output power, Net ID, Node ID. Users can configure the parameters through PC or customer’s own device. The features of long distance, wide working voltage and simple parameters configuration make SNR651 wildly used in many fields.
