EMS-ARH
Series: EMS
The Avalue EMS-ARH is a modular computing system powered by Intel Core Ultra processors (Series 2, Meteor Lake-H) — Core Ultra 7 255H / Ultra 5 225H — with integrated Intel Arc GPU and NPU for AI-accelerated edge workloads. Dual SO-DIMM sockets support up to 64GB DDR5 6400 MT/s, with dTPM 2.0 and optional Intel iAMT for secure, manageable deployment based on the EMS-ARH SBC. Its IET modular interface (DDI, 4 x PCIe Gen4 x1, USB 2.0, SMBus, eSPI) plus triple M.2 (Key-B/E/M, NVMe Gen4 x4) make it highly expandable. The EMS-ARH offers 2 x COM RS-232/422/485, 8-bit GPIO, four rear USB 3.2 Gen1, dual LAN, DP++ and dual HDMI, terminal-block power input, and rich LED/antenna provisioning — well suited to AI vision, machine control, and modular edge systems running Windows or Linux.
