Jeyway provides support for Windows 11 64-bit and Linux for the motherboard. The company provides a user manual, BIOS firmware files for PTT and dTPM, plus Windows 10/11 and Linux drivers for the NPU, GPIOs, audio, Ethernet, the chipset, and more. You’ll find all those in the product page linked at the end of this article.
It’s the second revision of the ATX-ARS1 motherboard, as the first model relied on a Q870 chipset. The ATX-ARS1-Q870 is suitable for standard industrial automation, but the ATX-ARS1-W880 targets “mission-critical equipment” for robotics control, medical equipment, and servers thanks to DDR5 memory with ECC support.
While it’s the first Arrow Lake-S ATX motherboard we’ve covered here on CNX Software, MSI previously introduced the MS-CF20 V2.0 (also with W880 chipset), and DFI unveiled the ARS630 ATX motherboard with Q870/W880 in August 2025. Another Arrow Lake-S hardware platform is the smaller Avalue EPI-ARLS 4-inch “EPIC” SBC limited to 35W parts.
Jetway has not provided availability and pricing information for its ATX-ARS1-W880 Arrow Lake-S ATX motherboard. More details, including a user manual, the BIOS, and drivers, can be found on the product page.
