New XL External Display Case 2.8 for Cardputer Adv

Description

This is the XL version of my alternative case concept for the M5Stack Cardputer Adv with an external 2.8 inch SPI TFT display.

The original version was designed for a 2.4” ILI9341 display, but this updated version uses a larger 2.8” screen with a redesigned upper display housing.

Like the original project, this design replaces the original bottom cover with a fully reversible custom solution that integrates the hinge mechanism directly into the case.
The display opens like a Nintendo DS while keeping the whole mod clean and modular.

Key Features

* Redesigned top section for a 2.8” display
* XL version of the original Cardputer ADV display mod
* Nintendo DS-style opening mechanism
* Fully reversible modification
* Designed specifically for Cardputer Adv

Hardware & Assembly

* Display: 2.8” SPI TFT display
* Hinge axis: M3 screws
* Display mounting: M2 screws
* Wiring must be adapted manually
* The 2.8” display PCB must be shortened by approximately 6 mm to fit the case correctly (see reference photos)

Printing Notes

* Supports required
* Drill hinge holes with a 3 mm drill after printing
* Carefully clean support material around small holes and hinges

Important Notes

* This is still an experimental prototype
* Geometry and mechanics may change in future versions
* More improvements and cable management updates are planned
