Connectors Pin-out
How to identify pin number 1: Looking to the solder side (The board
side without components) of the PCB (Printed Circuit Board), pin
number 1 will have a squared pad
pad
.
How to identify other pins: Connectors type DB, PS/2, RJ45, Power
ATX and USB are industry standards. DB connectors, for instance, are
numbered sequentially. The first row is numbered in sequence (be
aware that male and female connectors are mirrored – male connectors
are numbered from left to right when viewed from front and female
connectors are numbered from right to left when viewed from front).
The following rows resume the counting on the same side of pin
number 1. The counting is NOT circular like Integrated Circuits (legacy
from electronic tubes).
1 2 3 4 5
6 7 8 9
Header connectors are numbered alternately, i.e. pin number 2 is in the
other row, but in the same column of pin number 1. Pin number 3 is in
the same row of pin 1, but in the next column and so forth.
