Lantronix Cellular IoT GatewayEach gateway is pre-configured with Lantronix’s ConsoleFlow cloud-based device management and comes with a web-based user interface to configure networking (WiFi, Ethernet, Cellular, VPN, routing…), security (firewall, VLAN, SIM pin, etc.), and industrial communication protocols which include EtherCAT, DLMS Client, DNP3 Outstation, Modbus Master, IEC104 Slave and IEC 101 Master.

Although not specified in the description, the Lantronix G520 series Cellular IoT Gateways clearly run OpenWrt as the company offers a G520 SDK for building custom packages and creating custom firmware images, and the documentation assumes that “you have a computer running a supported Linux distribution (or VM) and are familiar with the OpenWrt build system and Lantronix Web Admin to configure G520 series devices.

The G520 Industrial (G526) and G520 Security (4G LTE: G527, 5G: G528) gateways are available now, while G520 Transport (G529_) will arrive later this year. Pricing has not been publicly disclosed, and more details can be found in the press release and on the product page.
