This is a display case for WeAct 2.9-inch e-ink screens:

The enclosure has enough space to hold the ESP32 controller, cables, and other electronic components. There are adequate ventilation openings around the edges to keep the components cool. The back features holes suitable for using a micro USB or USB-C cable to power the controller, as well as a larger hole for running other items out of the enclosure (in the picture, it’s used for the thermometer display; the thermometer part is taken out of the enclosure to improve accuracy).

The component fits the A1 Mini print board; you just need to slide it into the bottom of the casing on top. It can be easily removed for repairs later on.
