Instead of making a wire connection, you can solder a 1×3 male header to the buzzer jumper holes
to allow the use of a shorting block for connecting the buzzer. You can also use male headers and
shorting blocks for the battery level jumper and compass jumpers if you have an Arduino Leonardo
or an Arduino Uno with an SMD (surface mount) microcontroller. However, there is not enough
clearance to use male headers on the battery level and compass I²C jumpers if you are using an
Arduino with a DIP (through-hole) microcontroller.
6.
Optional:
At this point, you might consider soldering additional components (such as sensors), or
headers or wires for connecting them, to the shield. If you do this, please check to make sure your part
placement does not interfere with the shield’s ability to mate with the Arduino or the chassis. In particular,
note that only components in the outermost three rows of the front expansion area can extend below the
board (the fourth front-expansion row can only be used for pins extending above the board), and if you add
any through-hole parts to the prototyping areas on the shield, you will need to drill corresponding holes in
the acrylic spacer plate for the leads to fit into.
Motors
7. Cut two of the included jumper wires in half to form four segments, and trim off the ends that are covered
in adhesive (the adhesive could interfere with making a good electrical connection to the motor). These wire
segments will be used as motor leads.
8. Solder a pair of leads to each motor. You might find it helpful to make a small bend at the tip of each lead
to hook into the hole in the motor lead tab to hold it in place for soldering.
Warning:
holding the soldering
iron against the motor lead for more than a few seconds can start to damage the motor brushes, so try to be
