3.5-inch SBC takes quad-core Whiskey Lake-U for a spin

Aug 12, 2019 — by Eric Brown 3,937 views

Commell’s 3.5-inch “LE-37N” SBC features an up to quad-core, 8th Gen Whiskey Lake-U processor plus triple display support, 2x SATA III, 2x GbE, 4x USB 3.1 Gen 2, and M.2 and mini-PCIe expansion.

Commell, which has gone all out for Intel’s 8th Gen Coffee Lake chips with embedded boards including its 3.5-inch LE-37M, has now launched a 3.5-inch single board computer that supports the more power-efficient, 8th Gen Whiskey Lake-U processors. The user manual indicates the new LE-37N board runs Linux and Windows.

The LE-37N joins other 3.5-inch Whiskey Lake U-series boards including Congatec’s Conga-JC370 and ASRock’s SBC-350. There are also several Whiskey Lake boards with other form factors, including Aaeon’s community-backed UP Xtreme.

The LE-37N appears to support any Whiskey Lake U-series processor with a FCBGA1528 package, but defaults to the quad-core, 8-thread, 1.7GHz Core i7-8665UE with 8MB cache, 15W TDP, and 24-EU Intel Gen 9.5 HD Graphics. You can load up to 32GB of 2400MHz DDR4 via dual sockets.


For storage, you get dual SATA III interfaces and a mini-PCIe slot with mSATA support. There’s also an M.2 E-Key 2230 slot for a WiFi/Bluetooth module. Dual Intel-based GbE ports are also available.

Triple simultaneous displays can be accomplished via a 4K HDMI port, a DVI interface, an 18/24-bit single/dual channel LVDS connection, and a fourth display interface of your choice. One SKU offers 4K-ready DisplayPort while the other gives you a choice between VGA and a second LVDS. An LCD inverter and Realtek ALC262-driven HD audio interfaces are also onboard.

The LE-37N is equipped with 4x USB 3.1 Gen 2 ports, which means the real 10Gbps USB 3.1 as opposed to USB 3.1 Gen 1, which is the new name for USB 3.0. There’s also an RS232 COM port, as well as a second RS232 and 2x RS232/485/422 interfaces. Other internal I/O includes 4x USB 2.0, PS/2, 8-bit GPIO, and SMBus.

The 146 x 101mm SBC ships with a watchdog, an RTC with battery, a wide-range 9-35V DC input, and a cooler fan. It supports 0 to 60°C temperatures with 10%~90%, non-condensing humidity tolerance.

    Hello, Owner(s) of gizmos should consider reposting info about new boards when they are really available to buy… actually almost of all them are not available to buy and just go to oblivion as not being not available really/actually, just are curiosity,
    on’t know if and when. they will be available really .
