XScale-GPIO
The XScale-GPIO stackable I/O module provides a host of both analog and digital I/O functions on a single I/O module. This module plugs directly into the back of the XScale-Mini, XScale-Maxi, XScale-5.7, XScale-Magnum, and XScale-Extreme Embedded Single Board Computers. The module features (2) two RS-232/422/485 serial ports, (16) sixteen independent parallel I/O lines, (8) eight channels of 12-bit analog to digital converter, and (4) four channels of 12-bit digital to analog converter. The XScale-GPIO can be stacked along with any other XScale I/O module of your choice, including another XScale-GPIO, but the serial ports on only one XScale I/O module can be enabled and used.
