Milesight UF31, ARM Cortex-A55 1GB LPDDR4X 4G LTE 5G NR Dongle
The Milesight UF31 is a compact 4G LTE and 5G NR dongle designed to provide reliable cellular connectivity for industrial and networking applications. It combines a quad-core ARM Cortex-A55 processor with 1 GB LPDDR4X RAM and 1 GB NAND Flash for efficient device operation.
The UF31 supports 5G NR SA and NSA, 4G LTE, and WCDMA networks across a broad range of supported frequencies. Its four SMA cellular antenna connectors and Micro SIM slot provide the required interfaces for cellular network deployment.
For wired networking, the device provides one 10/100/1000 Mbps LAN port with full or half duplex operation and auto-sensing. It also includes GNSS support for GPS, GLONASS, Beidou, Galileo, and QZSS, making it suitable for applications that require both cellular connectivity and positioning.
The device provides USB 3.0 Type-C connectivity for power supply, network supply, and debugging. Its software supports IPv4/IPv6, TCP, UDP, DHCPv4/DHCPv6, HTTP, HTTPS, DNS, ARP, Telnet, SSH, and other network protocols, along with access control, port mapping, custom rules, Web, CLI, and DeviceHub management.
With an IP30 metal housing, compact 90 x 72 x 15 mm dimensions, and support for desktop, wall mounting, and DIN rail mounting, the UF31 can be deployed in various installation environments. Its 5-24 VDC power input, surge protection, reverse polarity protection, and -20°C to +50°C operating temperature range support practical industrial networking deployments.
