PC/II+dx  Single-board PC/104 Computer


PC/104 Embedded Control SBC
Megatel’s PC/II+dx is a PC/104 compliant single board computer with all of the features that made us famous! This board is a true single-board PC/104 solution, that is available with a broad set of options that can be mixed in any combination to maximize price and performance.

On-board options include: Super VGA & LCD panel output, Ethernet, up to 8MB of on-board flash, up to 128MB of Memory, up to 4 Serial ports and Parallel port, IDE and SCSI – all of which can be combined into a small rugged package with low power consumption.

The PC/II+dx utilizes a local bus architecture for its peripherals, which maximizes the processing power of the 486 central processor without the normal speed limitations of the ISA Bus. This local bus design is provided for the VGA/LCD controller to ensure maximum speed and a price that can't be matched.
