About This Poster

The chapter names the ILI9341 and GC9A01 as SPI-driven displays but never shows the physical header to wire — this poster gives that pinout for both a rectangular and a round display module.

How to Use

• Explore — hover or tap a numbered marker to read about that pin.
• Quiz — test whether you can identify each pin from a visual hint alone.
• Edit mode — open main.html?edit=true to drag markers and recalibrate positions once the poster image is generated.
