Description
Example of the kicad-display symbol repository being used to create a breakout board
README
kicad-display Breakout example
This repository contains a simple breakout board for a 1.69" IPS LCD with capacitive touch, and serves as an example of the KiCad project structure.
It was intended to be used with the following display from AliExpress, however this flat-flex cable is not solderable, and requires a FPC connector to be soldered onto the PCB. This was originally an oversight on my part, and the PCB that was produced did not feature this footprint, which required manual rework of soldering individual wires directly to the FPC. This version should be fixed, although it has never been produced.
Requirements
Pulling the repository
Remember to pull recursive submodules to include the display library if you are using git to clone the repository!
git submodule update --init --recursive

Footnotes
-
Note that R3 can be shorted by a solder bridge if you don't have a 0R resistor. This is an optional resistor to limit the current to the LCD backlight. The backlight consists of 3 LEDs in parallel and can pull up to 60 mA. With a 3V3 supply and a BJT as a switch, the voltage over the LED will be slightly below the nominal forward voltage of 3 V. ↩
