Linux-friendly μQseven module aims Bay Trail Atoms at IoT

Apr 9, 2015 — by Eric Brown 1,066 views

Seco is prepping a tiny, Linux-friendly, μQseven module for IoT with a single- or dual-core Intel Atom E3800 or Celeron SoC, and three PCIe lanes.

Seco’s μQ7-BT-J uses the same half-size, 70 x 40mm μQseven form factor adopted by its earlier µQ7-T30, µQ7-i.MX6, and µq7-OMAP5 computer-on-modules. This is the first μQseven module we’ve seen with an Intel Atom E3800, although there have been several full-sized (70 x 70mm) Qseven COMs that have tapped the 22nm SoC, including Avalue’s EQM-BYT and Arbor’s EmQ-i2301.

The Seco μQ7-BT-J runs Linux or Windows on a single-core Atom E3815, dual-core Atom E3825, or dual-core Celeron N2807. The module is touted as “the smallest Intel 64-bit SoC-based standard module on the market” and billed as a cost-effective “industrial Internet of Things basic building block.”

The tiny, SODIMM-style module ships with up to 4GB soldered DDR3L RAM, as well as optional soldered eMMC flash at up to 16GB. Dual display support is available via the Qseven edge-connector’s DisplayPort and LVDS connections.


The module supports a gigabit Ethernet port, as well as one USB 3.0 port and four USB 2.0 ports. There’s also HD audio, SD and SATA storage, and three PCIe expansion interfaces
