[Introduction]：EWM528-2G4NW27SX is a wireless serial port LoRa MESH networking module based on LoRa spread spectrum technology, with a maximum output power of +27dBm, a maximum air rate of 253Kbps, and a maximum supported baud rate of 2000000bps. The module operates in a frequency range of 2400-2500MHz (default 2400MHz). The LoRa MESH module uses the new LoRa MESH networking technology, with features such as decentralization, self-routing, network self-healing, and multi-level routing. It is suitable for smart homes and industrial sensors, wireless alarm security systems, building automation solutions, smart agriculture and other application scenarios.
