In the following picture you can see how the 3PDT pins should be positioned (inserting the pins in the holes can be a bit tight to avoid movement while soldering): 2- For a proper soldering you just have to apply the right amount of solder wire.
- Page 8 Building Tips 5- Pay attention to the parts that have a polarity and make sure they are connected as in the component placement picture: - ICs (they have a small dot or indication that must fit the indication in the board - Electrolytic capacitors (longer pin is connected to the “+”...
- Page 9 Building Tips 6- With the kit we include plastic PCB supports with an adhesive bottom. You can use them to anchor the PCB to your enclosure for a better stability. Just insert the PCB support tip into the 3.5mm holes and remove the adhesive protective film.
