Wiring diagrams

Pick your display and the modules you actually wired up.

Work in progress. This page is still being put together — some combinations are missing and the diagrams already here may change. Check them against your own board before you solder anything.
Every diagram shows the default pin map. One firmware fits any wiring — pins live in the device's web UI, so if yours differ, remap them at <device-ip>/setup instead of rewiring to match the picture.

Modules — the diagram has to include all of them
SPI panel + FT6336U

SPI panel + FT6336U

The full build: one wiring for every 4-wire SPI panel, only the panel module itself changes.

SPI panel + XPT2046

SPI panel + XPT2046

The full build with resistive touch — it shares the panel's SPI bus and adds its own CS.

No diagram covers that combination yet.
Drop a module or two — a diagram with more on it than you wired is still the right one to follow.
