ASRock Industrial SBC-375M Intel Core Ultra 5 125H 3.5″ Single Board Computer with Quad Display and 2.5GbE

Digital signage and machine-side HMIs often need four screens, a camera and a cellular link more than they need the top processor tier. The ASRock Industrial SBC-375M is the Core Ultra 5 build of the SBC-375 series, a 3.5″ single board computer with the same expansion as its Core Ultra 7 sibling.

The Core Ultra 5 125H is a Meteor Lake-H processor with four P-cores and eight E-cores, Intel Arc graphics and an NPU rated at 11 TOPS, which can take light inference off the CPU. One DDR5 SO-DIMM socket runs at 5600 MHz and takes up to 48 GB. Intel vPro is supported through the 2.5GbE port, a TPM 2.0 chip is on board, and the SBC-375M runs Windows 11 and Linux.

Networking is one Intel I226LM 2.5GbE port and one Intel I210AT Gigabit port. Up to four displays run from HDMI 2.1, DisplayPort 1.4a, two USB 3.2 Gen 2×2 Type-C ports with DisplayPort, and LVDS or eDP. Two USB 3.2 Gen 2 ports sit on the rear, and internal headers carry four USB 2.0, three RS-232/422/485 COM ports, four GPI and four GPO and a four-lane MIPI CSI-2 camera input. A PCIe x1 Gen3 slot, an M.2 E key for optional Wi-Fi and an M.2 B key with SIM slot for optional 4G or 5G cover expansion. Storage is two M.2 M key sockets on PCIe x4 Gen4 and one SATA3 port, with Intel VMD RAID 0 and 1.

Power is 12 to 36 V DC on a four-pin wafer, with AT and ATX modes. The board is rated from -20 °C to 70 °C operating and -40 °C to 85 °C storage, and carries CE and FCC marks. We supply the SBC-375M configured and tested, with DDR5 memory, storage, the OS image and any wireless modules and antennas fitted. The SBC-375P steps up to a Core Ultra 7 155H, and the SBC-373M-WT runs from -40 °C to 85 °C on a 13th Gen Core i5.
