ASRock Industrial IMB-1251-WV Intel Core Ultra Series 3 Industrial Mini-ITX Motherboards with ECC and 12-28V DC

Adding AI inference to an embedded system has often meant a GPU card or a separate accelerator, with the extra power, heat and enclosure space that brings. On current Intel processors much of that work can run on the processor itself, which keeps a design inside a Mini-ITX footprint and a DC power budget. The ASRock Industrial IMB-1251-WV series is built around that idea: industrial Mini-ITX motherboards on Intel Core Ultra Series 3 (Panther Lake-H) processors with a built-in NPU, wide DC input and the serial and display I/O embedded projects still rely on.

Every IMB-1251-WV board has two DDR5 SO-DIMM sockets in dual channel for up to 128 GB, with Intel In-Band ECC supported on both processor options. Storage is split across two M.2 Key M sockets, one on PCIe x4 Gen5 and one on PCIe x4 Gen4, plus two SATA3 ports, with Intel VMD RAID 0 and 1. Up to four displays run from two HDMI 2.1 outputs at up to 8K at 60 Hz, two DisplayPort 1.4a outputs over USB 3.2 Gen 2×2 Type-C and an LVDS or eDP connector. Networking pairs an Intel I219LM Gigabit port with a Realtek RTL8125BG 2.5GbE port, and an M.2 Key B socket with SIM and an M.2 Key E socket take optional 4G, 5G and Wi-Fi modules. Three internal RS-232/422/485 COM ports and four GPI and four GPO cover serial devices, with an optional DSC-8DIO001-WT module for eight isolated inputs and outputs.

The range splits by processor. The IMB-1251P-WV uses the 16-core Core Ultra X7 358H with Intel Arc B390 graphics and DDR5 7200, with AI performance rated at 50 TOPS, for vision, analytics and graphics-heavy signage. The IMB-1251E-WV uses the eight-core Core Ultra 5 325 with Intel Graphics and DDR5 6400, rated at 47 TOPS, for lighter inference and general embedded work with the same I/O. Both move on from the 12th Gen Core U-series processors of the IMB-1234 series.

In practice the IMB-1251-WV series suits edge AI systems, multi-screen digital signage and manufacturing equipment that has to fit a standard Mini-ITX enclosure. Power is 12 to 28 V DC through a four-pin cable or the rear DC jack, with a 12 V only build as a BOM option. The boards are rated from -20 °C to 70 °C operating and -40 °C to 85 °C storage, carry CE and FCC marks, and have a TPM header, Intel PTT and a watchdog timer, with an optional AI-M2-OOB module for out-of-band management. Windows 11 and Linux are supported, and we supply each of these industrial Mini-ITX motherboards configured and tested with memory, storage and the OS image fitted.
