I/O Module Digitally Expands SBCs
Designed for expansion on Pico-ITXe SBCs, the PCO-UIO48-G from WinSystems is a 48-point digital I/O interface with interruptible event sense. The module can monitor 24 of the rising and falling digital edge transitions, latch them, and then signal the host processor that a change of input status has occurred. Each I/O line is programmable for input, output, or output with read-back operation. The module requires 3.3 V. Operational temperature range is from -40°C to 85°C. The module lists for $59. A depopulated version with 24 lines, called the PCO-UIO24-G, lists for $49.
