[Introduction]：The E95-DTU (900LN22-485) is a LoRaWAN node radio that supports CLASS-A/CLASS-C node types and both ABP/OTAA network access methods. It supports LoRaWAN 1.0.3 standards (EU868/US915/AU915/AS923/IN865/KR920/RU864) and provides an RS485 interface. Users can easily connect to a standard LoRaWAN network via AT commands or a host computer. It supports transparent transmission and script-based timed data acquisition. It features a plastic housing, DIN rail mounting, and supports a wide voltage input range of 8–28V (DC). LoRa spread spectrum technology offers longer communication distances and strong anti-interference capabilities. The product is coated with a conformal coating, providing protection against mold, moisture, and salt spray.
