Installation 2.1 What is “COM Express”? With more and more demands on small and embedded industrial boards, a multi-functioned COM (Computer-on-Module) is the great one of the solutions. COM Express, board-to-board connectors consist of two rows of 220 pins each. Row AB, which is required, provides pins for PCI Express, SATA, LVDS, LCD channel, LPC bus, system and power management, VGA, LAN, and power and ground interfaces.
Page 15
Module Type 1 and 10 support single connector with two rows of pins (220 pins). Module Type 2, 3, 4, 5 and 6 support two connectors with four rows of pins (440 pins). EmETXe-i250C is a Type 6 module. Connector placement and most mounting holes have transparency between Form Factors.
