Embedded Open Modular Architecture/PCMCIA
PCMCIA form-factor Open Modular Architecture
This page describes the specification for re-purposing of the PCMCIA interface and form-factor as a portable Embedded Computing Module. Mass-volume "Lowest Common Denominator" interfaces have been chosen, all of which have existed for over a decade, but are low-power enough to be standard across virtually all mass-produced powerful Embedded CPUs. These interfaces are: 24-pin RGB/TTL (for LCD Panels), I2C, USB2, 10/100 Ethernet, and SATA-II. The interfaces have been specifically chosen because they are either essential or they are multi-purpose buses. The only interface which is not particularly common on mass-produced powerful Embedded CPUs is SATA-II: this can be constructed from a USB-to-SATA converter IC such as the Genesys Logic GL831A.
