Datasheet

Check your work, the connections should be solid and

shiny

Next up we will attach the 2x8 IDC header. Unlike the

2x20 header, this connector has a direction!

Notice in the middle there's an outline for the connector

in the middle. On the right it says HUB75 and on the left

of the connector there is a little 'cutout' shape. This

cutout shape must match up with the cut out on the

connector.

If you solder it in backwards, its not a huge deal, you

can use diagonal cutters to cut out a notch on the

opposite side, but if you get it right then you will never

have to worry about plugging in your matrix data cable

the wrong way
