Up to 4.3GHz, hexa-core Coffee Lake-H on tap in new 3.5-inch SBC

Jun 14, 2019 — by Eric Brown 3,357 views

Commell’s 3.5-inch “LE-37M” SBC showcases Intel’s 8th Gen H-series CPUs with triple displays, 4x USB 3.1, 2x SATA III, 2x GbE, and mini-PCIe and M.2 expansion.

Commell has latched onto Intel’s 8th Gen “Coffee Lake” product line and is holding on tight. Last August, Commell launched the LV-67X industrial Mini-ITX board and followed up with a 3.5-inch LS-37L SBC that similarly supports up to 65W TDP Coffee Lake S-series chips via a FCLGA1151 socket. The new LE-37M is a similar 3.5-inch Coffee Lake SBC, but with a few new features and an FCBGA1440 socket that supports Coffee Lake H-series with more embedded-friendly 45W TDPs.

Commell offers two choices: an LE-37M5 SKU with the quad-core, 8-thread Core i5-8400H clocked at 2.4GHz/4.2GHz and an LE-37M7 with the hexa-core, 12-thread Core i7-8850H clocked at 2.6GHz/4.3GHz. A QM370 chipset is onboard instead of the newer Q370 found on the S-series boards.

Like the earlier Commell SBCs, the LE-37M is accompanied by Windows drivers, but Linux support is mentioned in the manual. The LE-37M is designed for imaging, machine vision, infotainment, medical, and gaming machine applications.

The LE-37M gives you twice the RAM as the LS-37L with up to 32GB of dual-channel, 2666MHz DDR4. As before, you get 2x GbE and 4x USB 3.1 ports, as well as 2x SATA III ports and a mini-PCIe slot with mSATA and PCIe support. The SIM slot has been removed, but you get an M.2 E-key slot for general-purpose expansion.

Like the LS-37L, the LE-37M provides triple display support, but with a slightly different mix of features. There’s a new coastline VGA port (instead of a header) in addition to the HDMI port and headers for DVI, LVDS, and an LCD inverter. It also similarly offers a choice of DisplayPort or a second VGA or LVDS header (LS-37MT5 or LS-37MT7 SKUs).


The VGA port replaces the LS-37L’s DB9 COM port, and instead of 4x RS232 headers you now get two. As before, there are headers for 2x RS232/422/485, 4x USB 2.0, and HD audio, GPIO, PS/2, and SMBus. The system provides a 0 to 60°C range and has an even wider 9-35V power input.
