Rugged 3.5-inch SBC gives you choice of Kaby or Skylake U-series

Apr 5, 2018 — by Eric Brown — 716 views

IEI’s 3.5-inch “Wafer-ULT3/ULT4” SBC runs on Intel 6th or 7th Gen Core U-series CPUs, and offers triple display support, SATA III, 2x GbE, 4x USB 3.0, 2x mini-PCIe, and -20 to 60°C support.

IEI has launched a 3.5-inch SBC called the Wafer-ULT3/ULT4 that features Intel’s dual-core U-series processors including Skylake Core or Celeron (ULT3) or Kaby Lake Core (ULT4) chips. The system is aimed at transportation systems, including passenger information computers, but it would seem to fit a much wider range of embedded applications.

The 146 x 102mm Wafer-ULT3/ULT4 is available in six different models with different names ranging from a Wafer-ULT3-i3-R10 with a 6th Gen Core, up to 2.3GHz i3-6100U to a Wafer-ULT4-i5-R10 with an up to 3.5GHz, 7th Gen Core i5-7300U. The images here show the most affordable option of the six 15W TDP options: the Wafer-ULT3-CE-R10 with an up to 1.6GHz 6th Gen Celeron 3855U. No OS support was listed for the boards, which are identical other than their CPU models, but we imagine Linux or Windows will run just fine.

You can load up to 16GB of 2133MHz DDR4 SDRAM on one SODIMM socket and can order an optional second socket with 4GB or 8GB of DDR4, for a total of up to 24GB overall. The Wafer-ULT3/ULT4 is further equipped with dual GbE ports, a SATA 3.0 interface, and dual full-size mini-PCIe slots: one enables mSATA, and the other is paired with a SIM card slot.

Triple displays are available via a combination of coastline HDMI and VGA ports, an onboard LVDS connector, and an iDP interface co-laid with VGA that gives you a choice of HDMI, LVDS, VGA, DVI, or DisplayPort. Dual HD Audio interfaces are also onboard.
