ICE Module
3.1 Chapter Overview
This chapter describes pin assignments and I/O characteristics for COM Express
modules. The carrier board uses two 220-pin 0.5 mm fine pitch board-to-board
connectors. There are five different pin-out types currently defined by the COM
Express Specification. The preferred choice of the embedded computer industry is the
Type 2 pin-out and therefore the leading manufacturers have chosen to produce COM
Express Type 2 modules. This pin-out offers the best balance between older
technology such as PCI and Parallel ATA while providing the latest technologies
including PCI Express, Serial ATA and PCI Express graphics.
