Ultra-compact PC expands connectivity, power options

Jul 15, 2010 — by Eric Brown — from the LinuxDevices Archive — 5 views

Axiomtek announced a fanless embedded system that uses Intel's 1.1GHz Atom Z510 or 1.6GHz Z530 CPUs and measures just 5.2 x 3.8 x 1.87 inches. The “eBOX511-820-FL” includes gigabit Ethernet, CompactFlash storage, and four USB ports, and supports a wide range of power inputs, the company says.

The eBOX511-820-FL — said to be aimed at automotive, healthcare, entry-level gaming, and in-flight infotainment — is the latest in Axiomtek's long-running series of "eBOX" systems, which typically combine a previously released motherboard with a heat-sink-equipped case. The system is an upgrade to the eBOX510-820-FL announced a year ago, adding a second serial port, and a mic-in port, as well as accepting a greater range of power inputs.

The new eBOX511-820-FL is slightly taller than the 510-820-FL model, at 1.87 inches instead of 1.5 inches, but is otherwise similarly sized. Like the earlier model it uses Intel's 1.1GHz Z510 or 1.6GHz Z530 CPUs. Measuring just 14 x 13mm, with two-Watt TDPs, the processors are paired with the chipmaker's comparatively huge SCH US15W companion chip, as usual.

Like the eBOX510-820-FL model, the 511 version derives its small size from its use of a pico-ITX format motherboard, Axiomtek's PICO820. When it was first released in September 2008, the PICO820 was claimed to be the world's first pico-ITX SBC (single-board computer) packing an Atom CPU. (For more background on the PICO820 and the Pico-ITX standard, please see our earlier coverage of the eBOX510-820-FL, here.)

According to Axiomtek, the eBOX511-820-FL accepts up to 2GB of memory via a single SODIMM slot, and has an internal CompactFlash slot for mass storage. The front of the device, as pictured above, has four USB ports and two serial ports, up from one serial port in the eBOX510-820-FL. There is also an audio jack with both line-out, and now, mic-in support, as well as a PS/2 connector for a keyboard and/or mouse.

The rear, as shown below, has a power switch, a VGA output, and a gigabit Ethernet port. In addition, the rear panel offers an external 25 Watt wide-range DC power connector, supporting inputs of 10VDC to 30VDC, compared to 5VDC only in the previous model. This wider range power supply may be one reason for the 0.4-inch taller chassis, and the increase in weight to 1.32 pounds.
