ASRock Industrial NUC-255H Intel Core Ultra 7 255H NUC Board with Quad Display and Dual 2.5GbE

Equipment builders who manage fleets of units in the field often want remote management and a familiar SATA drive option as much as raw speed. The ASRock Industrial NUC-255H is the Core Ultra 7 board in the NUC Ultra 200 Motherboard Series series, a NUC board on Intel Arrow Lake-H with Intel vPro support, two 2.5GbE ports and a SATA port alongside its NVMe sockets.

The Intel Core Ultra 7 255H has 16 cores (six performance and eight efficient) rated at 28 W, with Intel Arc 140T graphics and an Intel NPU rated at 13 TOPS. That suits the NUC-255H to graphics-heavy signage and lighter AI inference next to application code. Two SO-DIMM sockets take up to 96 GB of DDR5 6400, and Intel PTT firmware TPM and a watchdog timer are built in.

Networking is two Intel 2.5GbE ports, an I226LM on LAN1 and an I226V on LAN2, and ASRock Industrial lists Intel vPro support for the board. Up to four displays can run at once from two HDMI 2.1 outputs, DisplayPort 2.1 through a USB4 port with Thunderbolt 4 support and DisplayPort 1.4a through a USB 3.2 Type-C port, each rated up to 4K at 60 Hz. Three USB 3.2 Gen2 Type-A ports, a combo audio jack, two internal USB 2.0 and one internal RS-232/422/485 header cover peripherals. Storage is two M.2 Key M sockets on PCIe Gen4 with Intel VMD RAID 0 or 1, plus one SATA 6 Gb/s port, and an M.2 Key E socket with CNVi takes an optional Wi-Fi and Bluetooth module.

Power is 12 to 24 V DC through a DC jack, with AT and ATX power-on modes. The NUC-255H is rated from -20 °C to 70 °C and stores from -40 °C to 85 °C. We supply it configured and tested, with memory, storage and the OS image fitted. The NUC-225H offers the same board design with a Core Ultra 5 225H, the NUC BOX-255H puts the same processor in a complete NUC mini PC, and the NUC-1360P/D5 is the earlier 13th Gen Intel Core NUC motherboard.
