NOTE:
The headers must be at 90°
to the circuit board. It is necessary
to ensure that they remain
perpendicular or the Teensy’s pins
will not fit into the header pin
holes.
NOTE:
Both sockets have direction indicators
on them. Ensure they match the direction
indicators on the board (the little curved part
of the marking on the board). This is to ensure
the 74HCT245s are inserted correctly.
