Lantronix G520 cellular gateways target industrial communication, cybersecurity, and transportation

Lantronix G520-series 4G LTE Cat 4 and 5G cellular gateways are designed to address challenges in Industry 4.0, security, and transportation markets with three/four separate gateways all based on an unnamed ARM926EJ-S-based CPU running at 600 MHz that’s most likely Microchip SAM9X60 processor introduced in 2020.

All gateways are from the same base with variation for specific markets:

  • G526 Industrial Gateway with LTE Cat 4 Ethernet, Serial, I/O, Fieldbus conversion, and other industrial protocols
  • G527/G528 Security Gateway with LTE Cat 13 or 5G, built-in cryptographic secure element and PSE-PoE
  • G528 Transportation Gateway (coming soon) with LTE Cat 4, GNSS, accelerometer, CAN Bus reading, and other tracking features

      • Concurrent GPS and GLONASS (security gateway 5G model)
  • USB – 1x USB Type-A host port
  • Serial
    • RS-232 full via DB9 connector
    • RS-485 via 5-pin COMBICON header
  • I/Os
    • 2x IOs with common ground via a 3-pin COMBICON header and a tool-less plug configurable as analog input or digital output
    • Input: 0V ~ 2.5V DC (Zero); 3V to 50V DC (One)
    • Output: open collector; 200 mA max.; 50V DC max.
  • Sensor – 3-axis accelerometer (STMicroelectronics LIS331DLH)
  • HW Security – Microchip ATECC608 secure element on security variant
  • Misc
    • 9x LEDs for power, connectivity, some user-programmable
    • RTC with 100-day data retention period, approximately 15 mWh lithium manganese battery (not functional below -20°C)
  • Power Supply
    • Input voltage – 10.8 to 60V DC via 3-pin Nano-Fit header
    • PSE-PoE+ for Security pack only (30W per LAN port)
    • “Last Gasp” with about 100 seconds of power via 2 96 mWh Li-ion batteries (not functional below -10°C)
    • Digital Input (Ignition) on the third pin of the 3-pin header

Lantronix Cellular IoT gatewayEach gateway comes 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 that include EtherCAT, DLMS client, DNP3 Outstation, Modbus master, IEC104 slave, and IEC 101 master.

While not specified in the description, Lantronix G520-series cellular IoT gateways clearly run OpenWrt as the company offers a G520 SDK to create custom packages and build 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 the Lantronix Web Admin for configuring G520 series devices.”

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