Identification of Pin 1
Unless otherwise stated, pin 1 of a connector is seated on a square pad that is different
from the round pads used for other pins. Sometimes, pin 1 is next to a trigonal mark on
the board. When there are two rows of pins on a connector, the row with pin 1 is
composed of odd numbers and the other is composed of even numbers.
Usually, there will be numbers or marks next to the pins of a connector on the board to
indicate the pinouts.
