Note that for the 30 way PCB edge connector, the top and bottom pin pads are electrically connected through the large via holes in the
middle. Hence there are only 15 connections effectively, with 30 pin pads. The PCB connector can be linked to your motherboard through the
via holes using standard 2.54mm pitch pin header.
