Support Waveshare ESP32-S3-Touch-LCD-5B

BotapSuggested this wish · —

I’d like to use the Waveshare ESP32-S3-Touch-LCD-5B as a Tessera screen. It’s a 5" 1024×600 capacitive touch display board with an ESP32-S3 (16 MB flash, 8 MB PSRAM), powered via a 7–36 V input.

I tested the board with ESPHome (YAML) and the display, touch and backlight all work. I can run further tests on my own hardware if that helps with adding support.

Board: Waveshare ESP32-S3-Touch-LCD-5B Status: display, touch and backlight confirmed working in ESPHome

Hardware testing

We often do not have this board ourselves. Community testing helps establish what actually works. A successful report is evidence for the maintainer to review, not an automatic compatibility claim.
