ASRock Industrial iBOX-255H Intel Core Ultra 7 255H Fanless NUC PC with Arc 140T Graphics and Dual 2.5GbE

Security monitoring, digital signage and edge AI vision often need solid graphics and plenty of local storage in a unit that runs without a fan. The ASRock Industrial iBOX-255H is the Core Ultra 7 255H model of the iBOX Ultra 200 Series series, a fanless NUC PC with Intel Arc 140T graphics, dual 2.5GbE and a SATA drive bay alongside two NVMe sockets.

The Core Ultra 7 255H is an Arrow Lake-H processor with 16 cores and Intel Arc 140T graphics. Two SO-DIMM sockets take dual-channel DDR5 6400 memory up to 96 GB. LAN1 supports Intel vPro Essentials, security comes from firmware TPM (Intel PTT), and the iBOX-255H supports Windows 11 and Linux, with a watchdog timer for unattended sites.

Storage combines two four-lane PCIe Gen4 M.2 M key sockets with a SATA 6 Gb/s port for an internal drive, and Intel VMD RAID 0/1 across the M.2 pair. Four displays run from two HDMI 2.1 outputs at up to 4K, DisplayPort 2.1 over the USB4/Thunderbolt 4 port and DisplayPort 1.4a over a second USB-C port. Three USB 3.2 Gen2 Type-A and two USB 2.0 ports, two Intel 2.5GbE ports (I226LM and I226V), one RS-232/422/485 COM port and a headphone and microphone jack complete the I/O. An M.2 E key socket takes an optional Wi-Fi and Bluetooth module.

Power is 12 to 24 V DC through a DC jack, with AT or ATX power-on modes and a 19 V adapter in the box. The fanless NUC is rated from -20 °C to 50 °C with 0.5 to 0.8 m/s airflow, stores from -40 °C to 85 °C and carries CE and FCC marks. It mounts by VESA, wall or DIN rail, with a wall-mount kit included and the DIN rail kit by request. We supply the iBOX-255H configured and tested, with memory, NVMe and SATA storage, the OS image and any Wi-Fi module fitted. The iBOX-225H uses a 14-core Core Ultra 5 225H in the same housing, and the NUC BOX-255H puts this processor in a fanned NUC with Wi-Fi 6E fitted.
