I still have problems with the displaydesc...
I have managed so far that everything is displayed where it belongs.
Only with the colors it does not work. Black is white, red is yellow, etc. and I don't really understand the concept of :R, :0, :1, :2 and :3 in relation to the colors.
Where do I have to do something to make something happen? 🤔

Not sure about tasmota here, but to my knowledge, the T-Dongle S3 uses inverted colors.

Did you manage to set up your device?

[SN-8023]

the silkscreen at least suggests that psram is present. is there a way to read it out?

[sfromis]

If Tasmota detects PSRAM present, it will report the available size in PS-RAM Memory near the bottom of the "Information" page in the web UI, and generally also something like this as first message after boot:
00:00:00.001 HDW: ESP32-S3 v0.2 (PSRAM)

On the chip itself (not really readable in your image), there should also be a nomenclature if the flash and PSRAM is on-chip, with the size after the letter "R" somewhere. Your board looks like having a separate flash chip, which then is not in the chip nomenclature.

[SN-8023]

then it probably has none... Too bad.

A reason for me talking about the nomenclature on the chip itself is that some variants are using octal PSRAM, needing a different build. If not using that, PSRAM cannot be detected at boot. Anyway, as the dongle is not a recent device, I'd not really expect it to have octal PSRAM. Should still be viable for basic usage.

[SN-8023]

it's a nice little dongle and for the size a lot of features, RGB LED (even if it's not a WS281x), TransFlash slot, display, wifi/bt...

the case could be a bit more premium for my taste, but it is what it is...
