COMMELL LV-683 miniboard based on T56N APU that integrated a low-power dual-core CPU and a discrete-level GPU(AMD Radeon HD 6320), providing one DDR3-1333 SO-DIMM SDRAM up to 8GB and an array of video interface including VGA, DVI and 18-bit single channel LVDS. The T56N APU supports single or dual-independent high resolution displays and exceptional multi-media capability with hardware decode support for H.264, VC-1, MPEG2, WMV, DivX and Adobe Flash.

The LV-683 comes with PS/2 Keyboard and Mouse, 1 x RS232/422/485 and 5 x RS232, 1 x Printer port, 4 x SATAII and IrDA interface on-board, Networking is provided by Intel 82583 Giga LAN, 10 x USB2.0 ports and HD Audio are also integrated.PCI 32-bit slot and one Mini-PCI slot and one PCIE mini card socket allows for easily using any wireless card or other add-on cards. Additionally, The operating voltage of LV-683 is from 5V to 24V DC that is ideal for vehicle computer applications or standard ATX power supply.
