# Plug pin locations
######################################################################
# Some micro-controller boards and displays use inconsistent labeling
# for the EXP1 and EXP2 headers. The following diagram shows the
# correct location of pin 1 along with ground and power pins on the
# EXP1 and EXP2 plugs:
#
# EXP1: EXP2:
# +-----------------+ +-----------------+
# | o o o o 5V | | o o o o o |
# | 1 o o o GND | | 1 o o o GND |
# +------ ------+ +------ ------+
#
# Some boards may have the cutout in the wrong location. If so, it may
# be possible to carefully pry the plastic header off of the pins with
# a small screwdriver, then correct the orientation and reapply the
# plastic header.
