1 Introduction The COM Express approach of custom carrier combined with off the shelf system cores is an excellent solution when you need to customize but lack the time or quantity for a complete redesign. It fits most system integration projects with production volumes from 500 to 10,000 pcs per year.
2 Special Features 2.1 Primary LPC based Super I/O Express modules do not contain any Super I/O because this is considered legacy. Therefore Super I/O is placed on the carrier board as an optional item. The Express-BASE uses a Winbond W83627HG-AW that supports FDD, LPT, COM and PS/2 Keyboard and Mouse.
6.2 Connector and Pin-out Compatibility Connectors positions and pin-outs comply with pin-out and signal description used in the original: “COM.0 - COM Express Module Base specification”. This document includes: description of pin- outs, signal descriptions and mechanical characteristics of the COM Express (Express) form factor.
