Featuring industrial-grade encryption, multi-protocol support (TCP, UDP, MQTT, HTTP, Modbus), and robust hardware capable of operating in extreme temperatures (-40°C to +85°C), it ensures reliable, secure, and flexible connectivity for professional IoT and industrial applications. ## Description E90-DTU(400SL30)E is a wireless gateway (Ethernet interface data transmission radio) that supports 10M/100M rate and based on LoRa communication technology and Ethernet protocol . Supports 2-way Socket, provides six working modes: TCP Server , TCP Client , UDP Server , UDP Client , HTTP Client , MQTT Client , and supports six client connections in TCP server mode . Wireless communication uses LoRa direct sequence spread spectrum technology, which will bring longer communication distances, and has the advantages of concentrated power density and strong anti-interference ability. It has a software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability. In the case of sudden interference, it can actively correct the interfered data packets, greatly improving reliability and transmission distance, and helping users to efficiently Complete long-distance data transparent transmission. Support users to perform relevant configuration through W EB web page and UDP host computer ## Features - Using the latest LoRa technology, it has a longer distance and more powerful performance than traditional LoRa data transmission radios;Adopts industrial -grade LoRa modulation technology, has data encryption, and the packet length can be set; Supports LBT function, the radio waits for transmission according to the current environmental noise intensity , improving the communication success rate of the radio in harsh environments; - Support wireless sending of command data packets, remote configuration and communication encryption; It can realize multi-level relay networking, effectively expand the communication distance, and achieve ultra-long-distance communication; Industrial grade design can work in -40℃～+85℃ environment, wide voltage input (DC 8 ～ 28V ); All-aluminum alloy shell, compact in size, easy to install and good in heat dissipation; - Perfect shielding design, good electromagnetic compatibility and strong anti-interference ability;RJ45 adaptive 10/100M Ethernet interface;Support multiple working modes ( TCPS , TCPC , UDPS , UDPC , HTTPC , MQTTC ); three configuration methods: configuration tool, web page, and AT command; Support 2-way Socket; Server mode supports up to 10 Socket connections ; Support DHCP function; Supports DNS (domain name resolution) and custom domain name resolution servers; - Supports a variety of Modbus gateways (simple protocol conversion, multi-host mode, storage gateway, configurable gateway, etc.);Supports quick access to Alibaba Cloud, Baidu Cloud, OneNET , and version 3.1 standard MQTT servers; Support HTTP protocol ( GET/POST request); Supports timeout restart function, time can be customized;Support short connection function, short connection interval can be customized; - Supports heartbeat package and registration package functions;Supports serial port cache cleaning function;Supports access to external networks, LAN, and virtual serial port tools;Support hardware restoration to factory settings and online upgrade ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #1,438 in Computer Networking Transceivers | ## Images ![433MHz Lora Wireless Data Transmission Ethernet Gateway E90-DTU(400SL30) E 30dbm Long Distance 10KM Modbus TCP-RTU MQTT - Image 1](https://m.media-amazon.com/images/I/41zDzwfqO0L.jpg) ![433MHz Lora Wireless Data Transmission Ethernet Gateway E90-DTU(400SL30) E 30dbm Long Distance 10KM Modbus TCP-RTU MQTT - Image 2](https://m.media-amazon.com/images/I/51ZrBs5A6mL.jpg) ![433MHz Lora Wireless Data Transmission Ethernet Gateway E90-DTU(400SL30) E 30dbm Long Distance 10KM Modbus TCP-RTU MQTT - Image 3](https://m.media-amazon.com/images/I/51kuUYZz8HL.jpg) ![433MHz Lora Wireless Data Transmission Ethernet Gateway E90-DTU(400SL30) E 30dbm Long Distance 10KM Modbus TCP-RTU MQTT - Image 4](https://m.media-amazon.com/images/I/511uLI9NCVL.jpg) ![433MHz Lora Wireless Data Transmission Ethernet Gateway E90-DTU(400SL30) E 30dbm Long Distance 10KM Modbus TCP-RTU MQTT - Image 5](https://m.media-amazon.com/images/I/515qE0sn2yL.jpg) ## Available Options This product comes in different **Color** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/811271662-433mhz-lora-wireless-data-transmission-ethernet-gateway-e90-dtu-400sl30](https://www.desertcart.com.br/products/811271662-433mhz-lora-wireless-data-transmission-ethernet-gateway-e90-dtu-400sl30) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-01*
