The UC-4400A Series is a family of compact Arm edge computers built for secure data acquisition, protocol conversion, and reliable telemetry in harsh industrial sites. Powered by a quad-core Cortex-A53 at 1.6 GHz with 4 GB LPDDR4 and 16 GB eMMC, each model balances efficient compute with rich connectivity: two auto-sensing Gigabit Ethernet ports, up to four software-selectable RS-232/422/485 ports, and up to two CAN 2.0A/B ports with 2 kV isolation. Four DI and four DO lines simplify integration with plant I/O.

Wireless options scale to the application. UC-443x variants accept LTE Cat 4 (mPCIe) and Wi-Fi 6E (M.2 E-key) accessories, while UC-445x variants add an integrated 5G Sub-6 NR modem with dual SIM and optional Wi-Fi 6E. GNSS, dual SIM, and antenna connectors are available on wireless-ready models for resilient connectivity and location awareness.

Security is baked in with TPM 2.0, secure boot, disk encryption, intrusion detection, security diagnostics, and compliance with IEC 62443-4-2 SL2. The metal IP30 enclosure supports DIN-rail or wall mounting. Power is redundant dual-input 9–48 VDC with reverse-polarity protection.

Designed for long service life, the series runs Moxa Industrial Linux (MIL3, Debian 11, kernel 5.10) with long-term support to 2031, one-step recovery, and dual-system failback. Environmental ratings cover -40 to 75°C for non-wireless, -40 to 70°C with cellular, and -30 to 70°C with Wi-Fi, alongside CE/FCC/UL approvals. From energy and EV charging to water, transport, and IIoT gateways, UC-4400A delivers a secure, adaptable platform at the edge.
