ADLINK provides support for Windows 10/11 IoT Enterprise 64-bit by default, and can also support Ubuntu 22.04 upon request.

Let’s have a look at the SBC-FM expansion connector. It’s comprised of two connectors a 50-pin Hirose FH34SRJ-50S-0.5SH(50) connector (position M below) and a 6-pin MOLEX 53398-0471 connector (position U) that are placed at opposite ends of the SBC35-ALN board. While the Alder Lake-N SBC supports PCIe Gen3 x1, USB 2.0, and SMBus, the SBC-FM connector also features PCIe Gen4 x4 and USB 3.0 for more powerful boards of the SBC35 series such as a SBC35-RPL powered by a choice of 13th Gen Raptor Lake processors.

FM stands for “Flexible Mechanical” and it’s designed to connect custom AFM (Adaptive Function Modules) with high-speed networking interfaces, additional USB ports, etc… through an FPC cable.

The expansion board can be placed on top or bottom of the SBC, as well as on the side as needed.

ADLINK does not provide pre-built SBC-FM-compliant Adaptive Function Modules for now, so it looks to be only for custom-designed boards for now, although I’d expect some SBC-FM modules to become available over time.

The company says the SBC35 series single board computers are suitable for a range of applications in automation, transportation, medical fields, and smart city projects, including Autonomous Mobile Robots (AMRs), Electric Vehicle (EV) charging stations, and self-service kiosks.

Pricing has not been made available publicly. More details may be found on the product page for the SBC35 series and in the press release.
