  • Page 11: Chapter 2 Product Overview

    The PC/104 architecture affords a great deal of flexibility in system design. You can build a simple system using only a CoreModule 420, with input/output devices connected to its serial or parallel ports, and a solid state disk drive or CompactFlash card in the respective bytewide socket, or CompactFlash socket.

  • Page 12: Product Description

    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, or it can be used as the computing engine in a fully customized application.
