CONNECTORFUNCTIONS
The board conformstoPC/104specificationsforthe four corners and four mounting holes.Wings, or
extensions on the left and right sides, provide additional room for I/O connectors.The wings extend
0.25”pastthestandardPC/104boardedgesasshownintheFigure1below.
The connector and jumper
layout is provided in Figures 1 and 2 below.This layout enables most
connectors to be positioned in the board wings and also provides sufficient clearance for the mating
