ASRock Industrial SBC-377 Intel Core Ultra Series 3 Panther Lake 3.5" SBCs with ECC, Quad Display and Dual 2.5GbE

A 3.5″ board used to mean a trade-off: enough compute for control and display, but little room for local inference or error-checked memory. The ASRock Industrial SBC-377 series changes that balance, putting Intel Core Ultra Series 3 (Panther Lake-H) processors with NPUs, In-Band ECC and PCIe Gen5 storage on single board computers that fit the same 3.5″ envelope as earlier ASRock Industrial boards such as the SBC-371.

Every SBC-377 model shares one board. Two DDR5 SO-DIMM sockets run in dual channel and take up to 128 GB, with Intel In-Band ECC supported on all CPU options. Two Intel 2.5GbE ports (I226LM and I226V) handle plant and camera networks, and up to four displays run from two HDMI 2.1 outputs, DisplayPort 1.4a over the USB 3.2 Gen 2×2 Type-C port, LVDS or eDP, and a second eDP 1.5 connector. Two M.2 M key sockets, one on PCIe x4 Gen5 and one on PCIe x4 Gen4, take NVMe storage with Intel VMD RAID 0 and 1, and an M.2 E key takes an optional Wi-Fi and Bluetooth module. Three RS-232/422/485 COM ports and four GPI and four GPO sit on headers. The rear panel adds two USB 3.2 Gen 2 and two USB 2.0 ports, with four more USB 2.0 on internal headers, and a Realtek ALC256 codec provides line-out and mic-in audio.

The range splits by processor. The SBC-377P carries the Core Ultra X7 358H, a 16-core processor with an NPU rated at 50 TOPS and DDR5 7200 memory, for vision and inference work that needs the extra cores. The SBC-377E uses the Core Ultra 5 325, an eight-core processor with an NPU rated at 47 TOPS and DDR5 6400 memory, which suits signage and lighter AI tasks.

In practice the SBC-377 series suits machine vision cells, multi-screen signage, edge AI appliances and manufacturing equipment. Power is 12 to 36 V DC on a four-pin wafer or up to 100 W USB Power Delivery through the Type-C port, operating temperature is -20 °C to 70 °C, and storage temperature is -40 °C to 85 °C. AT mode powers the board on as soon as input is present, with ATX mode for button start, and the boards carry CE and FCC marks. Windows 11 and Linux are supported, so these 3.5″ SBCs can run the same software stack as a larger edge computer.
