3.5-inch SBC targets thermally constrained display devices

Oct 27, 2009 — by Eric Brown — from the LinuxDevices Archive — 13 views

Commell announced a 3.5-inch single board computer (SBC) equipped with the thermally enhanced, automotive-focused Intel Atom Z510P CPU. The LE-375 provides gigabit Ethernet and includes support for 3D graphics, H.264 video acceleration, and dual displays, says Commell.

The LE-375 is built around the 1.1GHz Intel Atom Z510P CPU. This automotive-targeted version of the original Z510 is equipped with heat spreaders, making it suitable for thermally constrained fanless applications and restricted spaces, says Intel.

Commell's LE-375

Like the 5.25-inch, Atom N270-based LE-575 SBC recently introduced by Commell, the LE-375 targets display-oriented applications, but with a special focus on environments that take advantage of the Z510P's special capabilities. Applications listed for the LE-375 include in-vehicle infotainment, as well as industrial control and automation, gaming, diagnostic and therapeutic medical devices, media phones, and retail and transaction solutions.

The Z510P is joined by an Intel System Controller Hub US15WP, which, like the CPU, ships with embedded lifecycle support. The LE-375 further provides a SODIMM memory slot for up to 2GB of DDR2 SDRAM, and also supplies both CompactFlash and SD slots for flash expansion, says Commell. In addition, an IDE interface is said to support a 44-pin DiskOnModule with +5V power supply.


The SCH US15WP chipset provides the GMA500 graphics engine, with support for shadier-based 2D and 3D graphics. The chipset offers 256MB of shared display memory, plus hardware acceleration of H.264, MPEG2, MPEG4, VC1, and WMV video, says Commell.

The LE-375 is said to offer an LVDS interface as standard, and also is optionally available with either a VGA port or a DVI port. When either of these ports is fitted, the board supports dual displays, according to Commell.

Other external "real-world ports" include a gigabit Ethernet port, COM port, VGA/DVI port, PS/2 port, and two USB 2.0 ports. Internal interfaces, meanwhile, include four more USB 2.0 ports, RS232/422/485, and additional I/O. A PCI Express Mini Card socket is also supplied.

The "3.5-inch" LE-375 actually measures 4.0 by 1.8 inches, and works via DC power supplies from 9 to 24 Volts. The board supports temperatures of up to 140 degrees F, says the company.
