Lantronix X300 Compact Cellular IoT Gateways

Lantronix X300 Compact Cellular IoT Gateways offer extensive communication with LTE M or Cat-1 cellular, Wi-Fi®, BLUETOOTH®, Ethernet, and serial interface in a small, industrial-grade. The X300 cellular compact IoT gateway solution combines IoT gateway hardware, including centralized device management, cellular data, enhanced security, and expert technical support. These gateways operate at a  9VDC to 30VDC voltage range and -30°C to 70°C temperature range. The gateways consist of a 3-pin Nano-Fit™ header with brushed aluminum alloy. These gateways provide compact industrial-grade design, multiple hardware interfaces, latest cyber security protection, expert technical support, premium Console-Flow device management, and advanced hardware replacement. Typical applications include remote access, Wi-Fi gateway, BLE gateway, and industrial protocol.
