Missing information for OV5640 camera on diymore ESP32

[Creedy]

Hi
I am a total ESP32 noob, so I hope my question makes sense for you guys and that you are able to help me!

I have bought two ESP32 development boards with an integrated Ov5640 camera from amazon.de:
https://www.amazon.de/dp/B0DXFF1GKV?ref ... title&th=1

Unfortunately the ONLY information supplied with the bundle was the following "manual":
8.217.75.21/Industrial/Multilingual/CBAA0046-030_UK.pdf

So no information on specifications of pins for the camera, so I don't know how to setup the camera to actually work.
I have tried contacting diymore.cc, but there are no response on their Chat or Support email, so I don't know how to get more information about the specifc board and camera.

I know that the board is capable of outputting a stream, because I haven't uploaded new code on one of the devices. So I can connect to the AP created by the ESP32 (192.168.1.4) and view a simple stream (no settings are available on the screen).

I have tried the CameraWebServer Example in Arduino IDE, but none of the Board definitions works for this specific board, and I have no idea how to find out which pins the OV5640 camera are connected to.

Do any of you know how I can find out the pin connections or how I can get additional information for this specific board+camera combo, so I can get started on my project?
