E52-400NW22S LoRa MESH wireless module ad hoc network industrial grade self-routing network self-healing

[Introduction]:E52-400NW22S is a wireless serial port LoRa MESH networking module based on LoRa spread spectrum technology. The maximum output power is +22dBm, the maximum air rate can reach 62.5K, and the maximum supported baud rate is 460800 bps. The default working frequency band of this LoRa module is 433.125MHz. It adopts the new LoRa MESH networking technology and has the functions of decentralization, self-routing, network self-healing, and multi-level routing. It is suitable for smart homes and industrial sensors, wireless alarm security systems, and buildings. Automation solutions, smart agriculture and other application scenarios.
