Rugged PCI/104-Express SBC runs Linux on Skylake CPUs

Sep 5, 2017 — by Eric Brown — 1104 views

Adlink’s Linux-friendly “CMx-SLx” PCI/104-Express SBC offers 6th Gen CPUs, triple displays, plus shock, vibration, and optional -40 to 85°C support.

Adlink’s CMx-SLx is the first PC/104 form factor SBC we’ve seen that runs Intel’s 6th Generation Core “Skylake” CPUs. The 117.4 x 96mm PCI/104-Express Type 1 SBC runs Yocto-based Linux, Windows 10/7, VxWorks, or QNX on a dual-core 1.9GHz Core i3-6102E with 25W TDP, with optional 2.7GHz Core i3-6100E or up to 2.8GHz Xeon E3-1505L. Although these are lower end Skylake chips, you still get high-end Intel Gen 9 graphics with OpenGL 5.x, OpenCL 2.x, DirectX 12, and much more.

The CMx-SLx provides ruggedization features including 50G shock and 12G vibration resistance compliant with IEC 60068 and MIL-STD-202F standards. Both 0 to 60°C and BOM-optional -40 to 85°C models are available.

The CMx-SLx ships with 8GB or 16GB soldered DDR4-1867/2133 ECC RAM, as well as an 8GB SLC SATA-SSD, with options available at up to 32GB SLC or 64GB MLC. Two SATA III ports are available, along with dual GbE ports with WoL support, neither of which appear to be deployed as RJ-45 ports.

In fact, as is typical of PC/104 SBCs, there are only a few real-world coastline ports. These would appear to be the sole USB 3.1 port, as well as the DDI-driven, Intel HD Audio enabled mini-DisplayPort and micro-HDMI port. Triple simultaneous displays are available when you throw in the 18/24-bit single channel LVDS or optional eDP connection.

In addition to the USB 3.1 port, you get 6x USB 2.0 interfaces if you include the 2x interfaces available the PCIe/104 bus interface. The CMx-SLx supplies 4x PCIe x1 and 1x PCIe x16 (PEG) connections, with the latter configurable as 2x PCIe x8 or 1x PCIe x8 + 2x PCIe x4. The SBC also provides PCI/104 and PCI/104-Express Type 1 stack-down expansion interfaces.

The CMx-SLx is further equipped with 2x RS-232 and 8x GPIO, plus SMBus and I2C interfaces. The board runs on a 5V AT or ATX input, and offers ACPI 5.0 power management. SEMA (Smart Embedded Management Agent) software for hardware monitoring and control is built in, and TPM is said to be available from the AMI EFI BIOS. Accessories include heat sinks, a heat spreader, and a cable kit.

Further information

The CMx-SLx appears to be available now at an undisclosed price. More information may be found on Adlink’s CMx-SLx product page.
