Overview
The ASRock Industrial NUC 300 Series expands mainstream edge computing with four platforms built on Intel Core Series 3 'Wildcat Lake-U' processors. The lineup pairs two complete mini PCs — the NUC BOX-320 and NUC BOX-304 — with two bare motherboards, the NUC-320 and NUC-304, for integrators building custom systems.
Powered by the Intel Core 5 processor 320 and Intel Core 3 processor 304, the platforms combine CPU, integrated GPU and NPU into up to 40 platform TOPS of AI acceleration. A single SO-DIMM slot supports up to 64 GB of DDR5-6400 with In-Band ECC, while dual 2.5GbE networking and Wi-Fi 6E cover connectivity.
The fanned mini PCs measure 117.5 × 110 × 49 mm and deliver triple-display output through two HDMI 2.1 ports and USB-C DisplayPort, with storage expansion across two M.2 Key M slots. The series targets digital signage, kiosks, human-machine interfaces and intelligent gateways.
Key Benefits
Up to 40 platform TOPS of CPU, GPU and NPU acceleration; 64 GB DDR5-6400 with In-Band ECC; dual 2.5GbE plus Wi-Fi 6E networking; triple 4K display output; and a compact 117.5 × 110 × 49 mm fanned chassis for embedded deployment.
Applications
Digital signage and kiosks, human-machine interfaces, intelligent gateways, industrial edge computing, retail and banking terminals, and embedded systems.
