First Flight Version 1.0
Printed: 1/26/2008
This illustration is a map to the pin assignments on the terminal blocks. This view is the same as
looking down on the top side of the flight computer with its “nose” end pointing to your right. The
terminals are the holes in the side of each pin position where you insert your connecting wires.
Note:
Make sure you loosen the attachment screws before trying to insert wires into the terminal,
and then tighten them down again to get a good electrical connection.
