| OAK 2020 embedded motherboard |
|
 Taiwanese embedded PC and appliance specialist AR Infotek is shipping a fanless-capable, x86-compatible embedded motherboard with top-mounted I/O connectors and external PC/104 expansion. The OAK 2020 lets users add PC/104 modules without changing the system chassis.

Mounting the I/O connectors perpendicular to the board creates a more convenient work environment. The external PC/104 slot, meanwhile, lets users reconfigure their systems without changes to the underlying system chassis.
Fanless for low noise and dust accumulation, and with support for DIN rail mounting, the OAK 2020 targets automation, telecommunications, vehicle transportation systems, industrial control, surveillance, unmanned management or control, building automation, and other general embedded applications.
The OAK 2020 powers ARInfotek's Pipal 2025, a complete embedded system with DIN rail chassis supporting externally mounted PC/104 expansion boards

The OAK 2020 is based on an AMD Geode LX-800 processor clocked at 500MHz. The processor has 64KB each of instruction and data cache, along with 128KB of L2 cache. It integrates typical northbridge features, such as display and memory controllers, and mates here as usual with AMD's CS-5536 southbridge chip.
The OAK 2020 has a single SO-DIMM slot supporting 266/400MHz DDR memory cards from 128MB to 1GB. Storage options include a 2.5-inch hard drive and/or a CompactFlash card, with the option to choose which serves as master when both are present.
The OAK 2020 offers an external VGA interface and internal 24-bit LVDS video connector. The former supports video resolutions up to 1920x1440, at 32bpp and 85Hz refresh rates. The latter provides 1600x1200 at 32bpp and 100Hz refresh rates.

Real-world I/O connectors offer a full complement of PC-style I/O, including audio I/O, RS-232/485, USB 2.0, and 10/100 Ethernet. Expansion (in addition to PC/104) includes a mini-PCI slot suitable for 802.11a/b/g wireless cards.
The OAK 2020 is totally compatible with Linux and Linux based operating systems. Linux drivers are available for the watchdog timer hardware, and for controlling the three system status LEDs. Additionally, a driver is available for using the system's push button as an event trigger (it also suppports reset and power modes).
Supported ACPI modes include software power off (ATX mode), wake-on-lan (S5), wake-on-keyboard (S1), wake-on-ring (S1), and wake-on-RTC alarm (S1). Suspend to RAM (S3) is also reportedly supported.
