[Introduction]：The E95-DTU (400LN22-485) is a wireless data transmission node radio designed using LoRaWAN technology. It supports CLASS-A/CLASS-C node types and both ABP/OTAA network access methods. It supports the EU433/CN470 standard of LoRaWAN 1.0.3. The radio provides an RS485 interface, allowing users to 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 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.
