3.5-inch baseboard supports Qseven 2.0 COMs

Feb 20, 2014 — by Eric Brown — 810 views

MSC announced a 3.5-inch form-factor baseboard for Qseven 2.0 COMs, offering extended temperature support and USB 3.0, HDMI, DP, serial, and I2S interfaces.

Those who want to prototype using the latest Qseven 2.0 computer-on-modules, including the new Intel Atom E3800-based MSC Q7-BT or i.MX6-based MSC Q7-IMX6 modules from MSC Technologies, have been limited by older Qseven 1.1 baseboards. Such boards often don’t support new and improved Qseven 2.0 signals including USB 3.0, HDMI, DisplayPort, serial, and I2S audio interfaces, says MSC. Now, MSC has built an MSC Q7-MB-EP6 board that supports both of these Linux-ready modules, as well as any Qseven 2.0 compliant COM.

Coastline ports on the 3.5-inch SBC form-factor (148 x 102mm) MSC Q7-MB-EP6 board appear to include dual gigabit Ethernet ports, an SD slot, a serial port, and DisplayPort and HDMI ports. The single USB 3.0 port and two of the four USB 2.0 ports also appear to be available as real-world ports. In addition to the RS232 DB9, there are internal RS232 and RS485 interfaces. A SATA connector is available, along with an mSATA port and a Mini-PCI-Express slot.


An LVDS display is supported by a JILI30 connector, while another connector controls LCD backlighting, including dimming. Aside from an onboard I2S audio out pin header, all the other onboard connections depend on the capabilities of the attached Qseven module. Pin headers are available for SMBus, I2C, SPI, CAN Bus, and either LPC Bus or GPIO, depending on the COM.

Qseven modules connect sandwich-style via an MXM connector on the reverse side of the MSC Q7-MB-EP6. This position “simplifies system design with direct thermal contact of the heatspreader to the chassis for optimum passive cooling,” says MSC. The board supports a wide 10-28VDC power range, and is available in both a commercial and extended (-40 to 85°C) version.

Specifications listed for the MSC Q7-MB-EP6 include:

  • Processor/COM — Any ARM or x86-based Qseven 2.0 module via underside MXM socket

    • SATA port
    • mSATA port for up to 256GB (also supports mSATAmini)
    • MMC/SD slot
  • Display:
    • HDMI port
    • DisplayPort (supports DP++)
    • LVDS (optionally eDP, depending on COM) via Jili30 connector
    • LCD backlight connector and controls (3.3/5/12VDC)
  • Networking — 2x gigabit Ethernet ports (1x direct to module, 1x via PCIe)
  • Other I/O:
    • USB 3.0 host port
    • 2x USB 2.0 host ports
    • Micro-USB OTG connector
    • USB host via pin header
    • USB via Mini-PCIe
    • 2x RS232 port (1x via pin header)
    • RS485 via pin header
    • SMBus, I2C, SPI, and CAN Bus via pin header when supported by COM
    • LPC Bus or GPIO, depending on COM
    • Audio out via pin header (I2S-based Freescale SGTL 5000 codec)
    • Fan controls via pin header
  • Expansion — Mini-PCIe socket (full- or half-sized) with USB support
  • Power — 10-28VDC via 4-pin connector; slot for DL2032 Li-Ion battery (optionally Goldcap)
  • Operating temperature — 0 to 70°C (-801 model); -40 to 85°C (-103 model)
  • Dimensions — 148 x 102mm (5.8 x 4.0 inches); 3.5-inch SBC form-factor
