Assembling notes
The mandatory step: Cut the signals from the CPU to the LCD.
Apply a little bit of tin on the bottom of the Bivert board, on the small pins (the color data pins from the CPU to LCD). Then you only need to heat up this pins without adding more tin.
*It’s recommendable to use a little bit of flux.
If you can’t center the module correctly, you can desolder the capacitor and solder it back again when the signals are correly soldered.
