Tiny COM Express module runs Linux on quad-core Atom

Feb 26, 2015 — by Eric Brown 1,184 views

Aaeon launched a transportation-focused “NanoCOM-BT” COM Express Type 10 Mini module based on Atom E3800 SoCs, with optional industrial temperature support.

The Linux-friendly NanoCOM-BT supports a variety of automation, medical, ticketing, kiosk, surveillance, and communications applications, but is primarily being promoted for use in public transportation devices. The 84 x 55mm COM Express Type 10 Mini module supports the full range of Intel Atom E3800 system-on-chips, as well as two related Celeron SoCs. Other Linux-ready Type 10 Mini modules that run the E3800 include the Arbor EmNANO-i2300.

Aaeon touts the NanoCOM-BT for its “shock resistant nature,” but offers no specs to back that up except to say the board’s components are “industrial graded” and its RAM is soldered directly onto the board. The 84 x 55mm module is, however, available with optional -40 to 85°C support — but only with the E3800 SoCs, not the Celerons.

The NanoCOM-BT supports up to 2GB DDR3L RAM, and there’s optional, onboard eMMC flash memory ranging up to 16GB. An Intel gigabit Ethernet controller is also available. Dual displays are supported with the available DDI and LVDS interfaces.

The module provides one USB 3.0 and six USB 2.0 ports. Other I/O expressed via the COM Express connectors includes dual SATA, dual serial, audio I/O, and GPIO. The module provides three PCIe lanes, as well as LPC Bus and SMB expansion buses.


You can choose between the standard, wide-range 7V to 20V power supply, or an optional 5V model. Both Linux and Windows are available, and Aaeon’s Hi-Safe Software coordinates watchdog timers, digital I/O control, and system monitoring.
