Mini-ITX boards combine 1.8GHz Atoms, optional Ion GPU

Mar 7, 2011 — by Eric Brown — from the LinuxDevices Archive — 31 views

IEI released two Mini-ITX single board computers (SBCs) featuring the Intel Atom D525 or dual-core D525, both clocked at 1.8GHz. The KINO-PVN-D4251/D5251 and KINO-PV-D4252/D5252 both support up to 4GB 800MHz DDR3 memory, SATA and CompactFlash storage, PCI and PCIe expansion, dual gigabit Ethernet ports, plus USB and serial connectivity, while the KINO-PVN model adds an Nvidia GT218-Ion graphics processor.

Atom-based Mini-ITX boards have progressed considerably in recent years, along with the Intel Atom itself, to the point that you can get a dual-core 1.8GHz Atom, an Nvidia GT218-ION GPU, and loads of I/O all in a tidy 6.7 x 6.7-inch package. The presence of the Ion on the KINO-PVN-D4251/D5251 is the key difference between the two models, though the Ion-free KINO-PV-D4252/D5252 has two more serial ports, and there are some differences in operating temperature range.

Both models support either the single-core D425 or dual-core D525 Atom processors. These cranked-up versions of the Intel "Pine Trail" series of chips offer faster 1.8GHz clock rates, but similarly integrate graphic processing on the CPU. This enables the KINO-PV to get by without the Ion, though it can't offer the multimedia oomph and higher display resolutions of by the KINO-PVN.

The KINO-PV provides 24-bit, dual-channel LVDS ports for a maximum resolution of 1920 x 1080. The KINO-PVN, however, taps the Ion's HDMI interface to support 1080p video quality, and offers a dual-link DVI-I interface supporting resolution up to 2560 x 1600, says IEI.

The KINO-PVN is also said to provide dual independent display support through various combinations of the provided VGA port, dual-link DVI-I interface, and HDMI port.

Both SBCs ship with dual DDR3 800MHz SODIMM slots for up to 4GB of memory, says IEI. Other standard features include PCI, PCIe, and mini-PCIe expansion slots, as well as dual SATA 3Gbps ports, and a Compact Flash (CF) Type II card slot, says the company.

Additional common features include dual gigabit Ethernet (PCIe) ports with ASF 2.0 support, eight USB 2.0 ports, one LPT port, and an audio port. While the KINO-PVN gets three RS-232 ports, the KINO-PV get two more ports for a total of five.

In addition, both models offer a configurable RS-232/422/485 port with auto flow control, says IEI. As shown in the images below, much of this I/O is extended to real-world ports on the coastline on both models.

Like other IEI SBCs, the boards ship with the company's "One Key Recovery" software for system recovery after unexpected system failure. One Key Recovery creates a full system backup on demand, as well as system restoration to a previously made backup with a single click, says the company.

Operating system support is said to include a variety of Linux and Windows releases. Supported Linux distributions include various versions of Red Hat, Fedora, Ubuntu, Debian, and SUSE Linux. Windows releases are said to include XP, XP Embedded, 7, CE 5.0/6.0, and Vista.
