ESP32-2432S028 USB-C 2.8-inch Touch Display Case

# ESP32-2432S028 USB-C 2.8-inch Touch Display Case

A two-piece case for the ESP32-2432S028 / S028R 2.8-inch 240×320 touch-display

board, commonly known as the Cheap Yellow Display (CYD). This version is

designed around the USB-C board revision.

The case has a clean front bezel, broad access to the USB-C port, microSD slot,

UART/power connection, speaker connection, and GPIO/JST headers. The rear

service opening provides access to internal headers and the BOOT/RESET buttons.

The display is held between four reinforced mounting posts using M3 machine

screws and standard M3 hex nuts. The nuts sit in recessed hex pockets on the

front of the bezel so they cannot rotate during assembly.

## Required hardware

- 4 × M3 × 16 mm machine screws

- 4 × standard M3 hex nuts

- Optional: 4 × thin M3 washers under the screw heads

- [Example ESP32 2.8-inch display board](https://he.aliexpress.com/item/1005006470918908.html)

M3 × 16 mm is the recommended screw length. M3 × 12 mm is too short to engage

the nuts, while M3 × 20 mm protrudes by approximately 4.5 mm.

## Print settings

- Layer height: 0.2 mm

- Walls/perimeters: 3

- Infill: 15–25%

- Supports: none

- Material: PLA, PETG, or similar

- Orientation: print both pieces with their large flat exterior faces on the

build plate

## Assembly

1. Press an M3 nut into each hex pocket on the front face of the bezel.

2. Place the display board into the front bezel.

3. Position the rear cover over the board.

4. Insert four M3 × 16 mm screws from the rear and tighten them gently.

Do not overtighten the screws against the PCB. Board layouts can vary between

batches, so a quick test fit is recommended before a final print.
