CONNECTORFUNCTIONS



TheboardconformstoPC/104specificationsforthe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”pastthestandardPC/104boardedgesasshownintheFigure1below.



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

connectorswhenlatchingconnectorsareused.AllI/OconnectorsareverticalexceptforthepowerI/O,

externalbatteryandoptionalRJ‐45.
