Product Description
The CoreModule 420 SBC is an exceptionally high integration, high-performance, 486-based PC
compatible system in the PC/104 form factor. This rugged and high quality single board system contains
all the component subsystems of a PC/AT motherboard plus the equivalent of several PC/AT expansion
boards.
In addition, the CoreModule 420 SBC includes a comprehensive set of system extensions and
enhancements that are specifically designed for embedded systems. These enhancements ensure fail-
safe embedded system operation, such as, a watchdog timer. It is designed to meet the size, power
consumption, temperature range, quality, and reliability demands of embedded applications. The
CoreModule 420 requires a single +5V power source.
The CoreModule 420 SBC is particularly well suited to either embedded or portable applications. Its
flexibility makes system design quick and easy. It can be stacked with Ampro MiniModules or other
PC/104-compliant expansion board, or it can be used as the computing engine in a fully customized
application.
