+# 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:

+# 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.
