3.5-inch SBC expands upon Skylake-H

Oct 19, 2016 — by Eric Brown 1,729 views

Commell’s 3.5-inch “LE-37I” SBC features Intel 6th Gen Core CPUs, and offers SATA 3, dual GbE, dual Mini-PCIe with SIM, and a wide-range power supply.

Like Commell’s 3.5-inch LE-37G single board computer, the LE-37I supports Intel’s 6th Gen (“Skylake”) Core processors, but this model uses the higher-end, mostly quad-core Skylake-H series processors rather than the LE-37G’s 15W, dual-core, 6th Gen U-Series chips. No OS support was listed, but Linux and Windows should run just fine.

The LE-37I uses the FCBGA1440 package and QM170 chipset, and supports Intel Core i3, i5, or i7 Skylake-H models. The only Skylake-H based 3.5-inch SBC we’ve covered is Avalue’s ECM-SKLH.

The 140 x 101mm LE-37I is designed for fanless embedded systems, including gaming, surveillance, medical, defense, signage, and industrial automation. Its wide-range 9-24V power supply also enables transportation devices, says Commell.


The LE-37I supports up to 16GB DDR4, and offers dual SATA 3 interfaces. The SBC can drive 4K resolution or triple displays via a wide variety of display interfaces including a coastline DisplayPort and HDMI port. Other coastline connections include dual GbE ports, four USB 3.0 ports, and an RS232 port.

Four more USB 2.0 ports are available internally along with five more serial ports, including an RS232/422/485 interface. Dual Mini-PCIe slots support mSATA and wireless, which is further enabled with a SIM socket. There’s also HD audio, GPIO, and more.
