Rugged Skylake Mini-ITX has 16.5mm profile

May 1, 2017 — by Eric Brown 1,376 views

Eurotech’s “CPU-521-17” is a -20 to 70°C ready thin Mini-ITX board that runs CentOS, Ubuntu, or Windows on Intel’s 6th Gen Core CPUs.

Eurotech has spun a variety of Linux-ready SBCs over the years, such as its i.MX6-based CPU-351-13, but the new 6th Gen Core “Skylake” based CPU-521-17 is the first Eurotech Mini-ITX board we’ve seen. Like the CPU-351-13 and most other Eurotech boards, the rugged, thin Mini-ITX board supports its Everyware Software Framework (ESF), a commercial version of the open source Java/ OSGi “Eclipse Kura” middleware for IoT gateways.

The CPU-521-17 runs CentOS 7, Ubuntu 15.10, or Windows 10 IoT Enterprise on Intel’s 6th Gen, dual-core U-Series Core i7, Core i5, and Celeron processors, each with 15W TDPs. Other similarly embedded-focused Skylake Mini-ITX boards include the Advantech AIMB-285, Congatec Conga-IC170, and Adlink AmITX-BW-I. All these boards have 20mm profiles, but Eurotech has whittled the CPU-521-17 down to 16.5mm.

You can order the 12V, fanless CPU-521-17 with up to 16GB soldered DDR3L for greater reliability. The board offers an extended -20 to 70°C range as well as optional conformal coating.


Coastline ports include 2x GbE, 4x USB 3.0, audio I/O jacks, and HDMI and DP++ ports, each with up to 4K support. You can run triple independent displays when you engage the 48-bit LVDS interface.

The CPU-521-17 is further equipped with 2x SATA 6Gbps ports with RAID 1/0 support, as well as 2x RS-232/422/485, 2x RS-232, 4x USB 2.0, and 8-bit DIO interfaces. Dual mini-PCIe slots are joined by a PCIe x4 slot and a SIM card slot. A watchdog, RTC with battery, and optional TPM are also available.
