- Soldering accoutrements (iron, solder, etc.)
- A small Phillips screwdriver
- Some steps may require wire cutters; see notes below.
After peeling, the parts may have a little bit of paper soot on them from laser cutting. They can be washed with soap and water, but be absolutely certain that everything is completely dry before assembly! We can work on the electronics in the interim…
Looking at the face of the LCD, with the backlight LED protruding from the right, we’ll be soldering to the header row across the top.
From the back, the USB and serial connectors should be along the outside edge, and the text on the backpack board is upside-down with respect to the LCD.
The pin strip has a long side and a short side. The long side of the pins should point back, to the header on the backpack board.
To help with alignment, temporarily insert one of the screws through the corner mounting hole on both boards.
Solder just the first and last pins on both front and back. Make sure both boards are aligned and parallel, and that the screw is pointed straight back. You can re-heat those four solder joints as needed while getting this alignment right.
Once everything is square and level, solder the rest of the header pins on both sides.
Let’s start with the end where the LCD backlight protrudes, it’s a little easier. The spacer for this end has an extra bite to fit around the backlight.
If everything looks good and straight, you can give all the screws an extra half turn or so to hold more firmly…but not so tight as to crack the plastic!
