This is the PCB I did recently

The PCB is plugged directly on the connector and is supplied at 5V with a little connector.
The board contains a SDCARD where you can store all the images / gifs

Hello, is it urgently necessary to an ESP32 S3?
Do some ESP32 Lolin have it, do they work?

Many greetings

No, it works only with the ESP32-S3.

Hello,
I'm currently struggling with the Oscillate instruction. I wanted to define a line for a scrolling text with DMAMATRIX.LIMITS. But it only moves the whole image. Is there an example program?
Best regards

Oscillate always move the complete image so you cannot scroll a single line.
You can print a text at different positions using DMAMATRIX.TEXT.POS x, y , clearing before with DMAMATRIX.FILL color, [x, y, width, height] so that, changing the y coordinate in a loop can show a scrolling text.
