Voltage Regulator
There is one voltage regulator (refdes REG1). It is marked KY5033. They have the same shape as a transistor, so
make sure that you look at the part marking to verify which one is the regulator,
Make sure that the flat side of the part lines up with the flat side of the outline on the PCB. Push the leads through the
holes, and bend the two outer leads apart to keep it in place while soldering. They will not sit flush against the PCB,
and that is fine. Do not force them.
Voltage regulators and transistors are more heat sensitive than most of the parts in this kit, so take care not to let the
soldering iron linger too long. If you are unsure, then solder one lead at a time and let the part fully cool off before
soldering the next lead.
Transistors
There are two 2N3904 transistors. They are marked on the PCB with refdes Q3 and Q4. There is no Q1 or Q2.
For soldering tips, refer to the paragraphs above relating to the voltage regulator.
Pushbutton
The pushbutton can only be inserted one way. The actuator (that you press) faces away from the PCB. It snaps into
place and will stay put while you solder it. Make sure it is fully inserted and seated flush against the PCB.
3.5mm Jacks
The eight 3.5mm jacks are inserted with their openings facing away from the PCB. The jacks do not snap in and will
not stay in place by themselves. Insert the jacks and flip the PCB over onto your work surface. They are the tallest
part on the PCB, so they will rest flat on your work surface. Solder only one pin of each jack. Then, check to make
sure each jack is flush against the PCB. If it is not flush, simply reheat the one solder joint while pressing the jack into
place. Once all jacks are all flush, go back and solder the other pins.
