Oct 24, 2007 — by Jonathan Angel — from the LinuxDevices Archive — 2 views

Aaeon has announced a “value-positioned” mini-ITX SBC (single-board computer) that can be used to create a media server. The EMB-820T is based on AMD's Athlon-family embedded processors, and features TV output and 5:1 surround sound, according to the company.

The EMB-820T is offered without a processor or memory installed, but accepts AMD's Athlon-derived NX1250, NX1500, or NX1750. Dual 184-pin DDR DIMM slots accept up to 2 GB of RAM, Aaeon says.

The board's graphics capabilities are implemented with an SIS 741CX graphics chipset. Its TV output serves up both NTSC and PAL video, while resolution is said to be up to 1600 by 1200 pixels on either a CRT or LCD. The LCD interface supports LVDS and 4-, 5-, or 8-wire resistive touchscreens.

The EMB-820T includes a Mini PCI slot that could, for example, be used to install a wireless network adapter. Unusually, the motherboard does not include Ethernet. Other expansion possibilities include a standard PCI card slot along with a Type II CompactFlash slot, and a floppy drive connector and 40-pin IDE connector.

Features and specifications cited by Aaeon include:

  • Processor — AMD Geode NX1250, NX1500, or NX1750
  • Memory — dual 184-pin DDR DIMM sockets, for up to 2 GB total DRAM
  • Display:
      resolutions up to 1600 x 1200 pixels
