Braid the wire and insert into a barrel jack connector. Secure the wires in the screw terminal with a
Phillips head. Feel free to add some heat shrink or electrical tape to the connection at this point.
Note:
Using screw terminals is one method of modifying the 12V/5V power supply. For a more
secure connection, try splicing the wires to a polarized connector and adding heat shrink to your
connection. You can also use a USB connector for the 5V side depending on your personal
preferences.
Test
the
Output
Power the power supply and test with a multimeter to verify the voltages. Usually power supplies are
center positive so make sure that the wires were inserted correctly. Adjust as a necessary for your
system.
