Lantronix E213F102S — Global LTE-M Dual SIM Industrial IoT Router

The Lantronix E213F102S is the global LTE-M version of the E210 Series industrial router. It is built for low-bandwidth, always-on connections such as remote monitoring, smart building controllers, payment terminals and industrial automation, where long-term reliability matters more than raw throughput. A single SKU covers LTE-M bands B1, B2, B3, B4, B5, B8, B9, B10, B12, B13, B17, B18, B19, B20, B25, B26, B27, B28 and B66, with 2G fallback, so one part number can be used for multi-country rollouts. The router pairs dual SIM (single standby, two mini-SIM trays) with configurable failover or load balancing across cellular, Ethernet WAN and Wi-Fi. SIM switching can be based on quality of service, and you can script your own switching conditions. Local connections include two 10/100 Ethernet ports (one WAN, reconfigurable as a second LAN), 1T1R Wi-Fi 4 as client or access point, a full RS-232 port on a 9-pin sub-D, and two user-configurable digital I/Os. An optional SC485 Snap Cap converts the serial port to isolated RS-485 for cable runs up to 1.5 km. On the software side, the E213 runs Lantronix's Linux-based ePack suite. It supports OpenVPN client/server, IPsec (up to 4 channels), WireGuard, L2TP, GRE and PPTP client, plus a zone-based firewall, VLAN and DMZ. Built-in converters translate Modbus RTU/TCP to IEC 60870-5-104, DNP3, MQTT, Azure and Cumulocity. You can build custom packages with the G520 SDK in Python or C/C++, and log data to microSD so the router only sends processed results upstream. The unit has a brushed aluminum housing of 92.5 x 57.2 x 22.5 mm and weighs about 150 g. It accepts 8–32 V DC input and operates from -20 °C to +70 °C. Lantronix publishes a product brief, a quick start guide and user guides for the series.
