[Introducción]:EWD95M-400NW22 (485) es un módulo de red LoRa MESH de puerto serie inalámbrico basado en la tecnología de espectro ensanchado LoRa, con una potencia de salida máxima de 22 dBm, una tasa de aire máxima de 62.5K y una velocidad máxima de transmisión admitida de 460800 bps. El módulo DTU de microrraíl tiene un rango de frecuencia de funcionamiento de 410,125 ~ 509,125 MHz (433,125 MHz predeterminado). La radio digital utiliza la nueva tecnología de red LoRa MESH, con características como la descentralización, el autoenrutamiento, la autorreparación de la red y el enrutamiento multinivel. Es adecuado para hogares inteligentes y sensores industriales, sistemas de seguridad de alarma inalámbricos, soluciones de automatización de edificios, agricultura inteligente y otros escenarios de aplicación.
