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 (433L30) E is a wireless gateway (10M / Ethernet interface) based on LoRa communication technology and Ethernet protocol. It supports 2-way Socket, provides six working modes of TCPS erver, TCPC lient, UDPS er ver, UDPC lient, HTTPC lient, and MQTT Client, and supports six-way client connection in TCP server mode. The wireless communication adopts LoRa direct sequence frequency expansion technology, which will bring further communication distance, and has the advantages of concentrated power density and strong anti-interference ability. With the software FEC forward error correction algorithm, it has high coding efficiency and strong error correction ability. In the case of sudden interference, it can actively correct the disturbed data packets, greatly improve the reliability and transmission distance, and help users to efficiently complete the transparent transmission of long-distance data. Support users can use WEB web page, UDP host computer for related configuration ## Features - ​​​​​​​Using industrial-grade LoRa modulation technology, with data encryption, subcontracting length can be set; Support for wireless sending of command data packets; Industrial grade design can work in-40℃ ~ + 85℃ environment D C 8~28V wide voltage input;RJ 45 Adaptive 10 / 100M Ethernet interface;Support multiple working modes (TCPS, TCPC, UDPS, UDPC, HTTPC, MQTTC); - Support configuration tools, web page, AT instruction three configuration ways; Support 2-road Socket; Server mode supports up to 6 Socket connections;Support the DHCP function; Support DNS (domain name resolution), and custom domain name resolution server; - Support a variety of Modbus gateways (simple protocol conversion, multi-host mode, storage gateway, configurable gateway, etc.); Support fast access to Ali Cloud, Baidu Cloud, OneNET, Huawei Cloud, 3.1 version of the standard MQTT server; - Support the HTTP protocol (GET / POST request); Support the timeout and restart function; Support the short connection function; - ;Support the heartbeat package, registration package function; Support access to external network, LAN, support virtual serial port tools; Support the hardware to restore the factory Settings and online upgrades ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #1,075 in Computer Networking Transceivers | ## Images ![Ethernet LoRa 433MHz Wireless Data Transmission Modem E90-DTU(433L30) E 30dBm Long Range 8km RJ45 UDP MQTT HTTP TCP Industrial - Image 1](https://m.media-amazon.com/images/I/41IDCDkequL.jpg) ![Ethernet LoRa 433MHz Wireless Data Transmission Modem E90-DTU(433L30) E 30dBm Long Range 8km RJ45 UDP MQTT HTTP TCP Industrial - Image 2](https://m.media-amazon.com/images/I/51ZrBs5A6mL.jpg) ![Ethernet LoRa 433MHz Wireless Data Transmission Modem E90-DTU(433L30) E 30dBm Long Range 8km RJ45 UDP MQTT HTTP TCP Industrial - Image 3](https://m.media-amazon.com/images/I/51Phje0bHEL.jpg) ![Ethernet LoRa 433MHz Wireless Data Transmission Modem E90-DTU(433L30) E 30dBm Long Range 8km RJ45 UDP MQTT HTTP TCP Industrial - Image 4](https://m.media-amazon.com/images/I/61Nm7J2h7vL.jpg) ![Ethernet LoRa 433MHz Wireless Data Transmission Modem E90-DTU(433L30) E 30dBm Long Range 8km RJ45 UDP MQTT HTTP TCP Industrial - Image 5](https://m.media-amazon.com/images/I/519cUIQrE+L.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.cy/products/811271662-ethernet-lora-433mhz-wireless-data-transmission-modem-e90-dtu-433l30](https://www.desertcart.com.cy/products/811271662-ethernet-lora-433mhz-wireless-data-transmission-modem-e90-dtu-433l30) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-07-10*
