World's first Qseven COM based on 4th/5th-gen Intel Core?

Dec 21, 2015 — by Eric Brown 1,613 views

Commell’s Linux friendly “QE-E71” COM appears to be the first Intel Core based Qseven module. It supports both 4th Gen Haswell and 5th Gen Broadwell CPUs.

The QE-E71 appears to be the first Qseven COM packing an Intel Core processor. We have seen a number of Intel Atom, Intel Braswell, and AMD G-Series based Qseven modules, not to mention numerous ARM-based Qsevens, but Intel Core chips are more often found in COM Express form factors. The QE-E71 updates an earlier QE-E70 Qseven module with Atom E3845 and Celeron J1900/N2930 support.

The QE-E71 also stands out from the crowd with its support for two different generations of Intel Core processors. The device supports 4th and 5th Generation Intel Core processors available in U-Series models with the same BGA-1168 pinout. You can use Core i7, i5, or i3 U-Series chips from the 4th Gen Haswell family and the 5th Gen, 14nm-fabricated Broadwell family. Standard SKUs include dual-core i7-5650U, i5-5350U, and Core i3-5010U Broadwell processors.

Although no OSes were specified on the module’s product page or in its data sheet, we feel confident that Linux is supported. Other Commell devices include the Linux-friendly, Haswell based LV-67M Mini-ITX board from 2013. The QE-E71 supports applications including medical equipment, automation, gaming, and Internet of Things, says Commell.


The QE-E71 offers one of the lowest maximum RAM allowances of any recent Intel Core based module we’ve seen. You can choose between soldered 2GB or 4GB DDR3L-1600 configurations.

I/O on this Core-based Qseven COM is relatively limited in comparison to what you’ll find on typical Intel Core-based COM Express modules. There’s a GbE controller, dual SATA ports, and four USB ports split between 2.0 and 3.0 versions.

You can run triple simultaneous displays with the dual DDI ports and single eDP. Other features include audio I/O, four PCIe interfaces, and LPC and SMBus expansion. The 70 x 70mm, 5V module has a commercial temperature range.

LE-5Q0 carrier

Commell is offering the same 5.25-inch form-factor LE-5Q0 QSeven Carrier Board it provides for the QE-E70 module for the new QE-E71. The 203 x 146mm board is loaded with options.

At the base level, you get a GbE port, dual mini-PCIe slots, a SIM socket, and dual SATA ports, with two more SATA connections available internally. The LE-5Q0 is further equipped with two USB 3.0 ports (plus four more onboard USB 2.0) and an RS232 port, plus four more internal RS232 ports and an onboard RS232/422/485 interface. Additional onboard interfaces include I2C, PS/2, DIO, LPC, SMBus, and Realtek ALC262 HD audio.

Options include a setup with a Gigabit Ethernet WAN port and four GbE LAN ports. All the display interfaces are optional, including DVI, three DisplayPorts, and dual 24-bit, dual-channel LVDS. Also optional are the SD slot and mSATA interface. You can choose between a 24-pin ATX power supply or 6~27V wide range DC input.

Further information

No pricing or availability information was provided for the QE-E71 Qseven module, although the LE-5Q0 carrier board has long been available. More information may be found on Commell’s QE-E71 and LE-5Q0 product pages.
