Overview
The ARBOR ARES-1990 Series is a 1U ultra-slim fanless box PC built on the Intel Core 5 120U processor. It is designed for edge AI and industrial networking roles where rack-adjacent height, wide DC input and in-vehicle ignition control matter.
Three SKUs cover different connectivity needs. ARES-1990-LAN provides four 2.5GbE ports for multi-camera or segmentation duties, ARES-1990-CAN adds two 2kV-isolated CAN FD interfaces for vehicle and machinery buses, and ARES-1990-AI combines three 2.5GbE plus one GbE port with an M.2 M-Key 2242 slot intended for an M.2 AI accelerator module.
Memory scales to 48GB of DDR5, storage uses a PCIe 4.0 x4 M.2 slot, and video output covers DisplayPort, HDMI, optional VGA and USB-C DisplayPort Alt Mode - enough for four simultaneous displays. Eight digital inputs/outputs are available on a single DB9 connector, and 5G/LTE or WiFi can be added through the M.2 B-Key and E-Key slots.
Power input accepts DC 9-36V through a 3-pin terminal block with a dedicated ignition switch, so the system can be tied to vehicle ACC signalling. MIL-STD-810H vibration compliance and -20°C to 60°C operation suit rolling stock, AGVs and roadside cabinets.
Key Benefits
Ultra-slim 1U fanless format for space-constrained racks and cabinets; 2.5GbE port counts of three or four for high-bandwidth camera arrays; isolated CAN FD option for automotive and machinery integration; M.2 AI accelerator expansion for on-box inference; DDR5 up to 48GB and PCIe 4.0 NVMe storage; DC 9-36V with ignition switch for vehicle installs; MIL-STD-810H vibration and -20 to 60C operation.
Applications
Intelligent transportation and rail systems; traffic analytics and ANPR; multi-camera surveillance edge servers; autonomous mobile robots; industrial gateway and protocol conversion; kiosk and interactive terminal control.
