Chapter One- Soldering the components
Ready to start soldering?
In this chapter, we'll explain how to solder all the components. You'll see many photos that will lead you through the process and make it easy to follow.
Part One - Soldering the first two components
Display circuit board + 2 female header pins
Insert the pin header from the backside of the board
Turn the display board again
Make sure to create a volcano-like shape so that the base of the joint is filled with solder but the top is getting thinner and thinner.
Before you repeat this step for the other three pins, let's make sure your pin header sits at the right angle.
Adjust the header with your finger
After you adjust the header's first pin, it's time to solder the other three pins. Take your soldering iron and some solder and keep on soldering.
Your soldering joints should look like small volcanos - more solder at the bottom, less at the top
Insert the second pin header
If you successfully soldered both pin headers, your display board should look like this:
Part Two - Resistors
Main circuit board + 2 resistors
Resistors are standard passive two-lead electronic components that implement electrical resistance as a circuit element. Spencer needs these resistors so they can adjust signal levels and regulate current flow.
Remove the protective paper
Once you remove the paper, you'll have to fold the resistor legs so they bend right where the resistor is.
The resistor should easily be inserted if you bend the legs like this
Push the resistor all the way to the board
Face the board away from yourself when cutting the legs. If you cut them carefully, the legs shouldn't fly around, but make sure to face the board towards the table just in case.
Cut the resistor legs like this
Part three - soldering more pin headers
Main circuit board + 2 male pin headers
Use the pliers as support when soldering the header to keep the main board in balance.

Part four - Soldering the capacitors
Main circuit board + 2 capacitors
The polarity of the capacitors is indicated with the big white minus (-) sign on the capacitors (the big white stripe).
Match the polarity of the capacitor with the polarity marked on the board
Insert the capacitor
When you insert the capacitor, bend the legs of the capacitor so that it doesn’t fall out from the board while you’re soldering it.
Cut the remaining part of the capacitor legs with your diagonal cutter pliers
Insert the second capacitor
Part five - Soldering the button
Main circuit board + button
There are only two pins that you have to solder here. The other two holes below the button should stay as they are. Please see the following photo to make sure you soldered everything correctly.
