Resolved by DJ Sures!
Some time ago I got a DEVELOPER KIT (EZB-v4) from a friend and already made the 3D prints for a JD and already realized some robot skills.
Unfortunately I don't have the EZ-B ROBOTIC CAMERA for this kit.
That's why I would like to install an M5Stack camera that I already have.
My question is, how can I connect my Unit CAM M5 with a UART interface with connector(GND,5V,G17,G16)?
I don't want to use WiFi for the connection, but only use the connector from the EZB-4 CTS, RTS, TX, RX, GND, 3.3V (6-pin JST-PH 2.0mm pitch).
Any help would be appreciated

You could connect that camera to the ezb v4 camera port, but the data it transmits will need to be modified for the same protocol.
I don’t know much about the camera you’re using. Is that camera an arduino programmable? If so, that could happen quite easily.
And they're SOOOOO expensive *eak*
Unfortunately, the Ezrobot developer kit was already used and therefore not complete, so I have to try it with another camera.
No no the camera is not an expensive model it is the (Unit Cam Wi-Fi Camera (OV2640) SKU: U109 Regular price$7.50)
and it has a programming platform: ESP-IDF/Arduino/UIFlow.
I also have a programmable USB TTL downloader but I don't know which program I could use to use all camera functions with the EZB-v4.
I would be glad if you could help me there.

Take a look at the firmware source code for the esp32cam: https://synthiam.com/Support/Hardware/ESP32-Cam
there’s a section where the jpeg of every frame is written to the tcp response. In your case it would be written to the uart
Now I had the opportunity to swap my camera for an ESP cam at my last workshop.
I installed the specified firmware on this camera and it works.
But now to my personal problem, I would like to use this camera "offline" in my JD because a WiFi connection is already available.
I would like to connect the camera via the "Camera Expansion Header" via the CTS,RTS,TX,RX,GRD,3.3V connections.
Is there a possibility?
I believe the ezb v4 camera also uses the rts line so you’ll need to set that as well.
The baud rate is 3,333,333
What do I have to write in the window where the IP address is so that I can get the camera image. if I go to "Costom" then it doesn't work either.
I think I will use the ESP32-camera for the further projects via WiFi.
Now I enter the same IP address as the EZB and it freezes image for 1-2 sec. given. Unfortunately I had to restart the EZB again to repeat that.
The debug output was always:
"Camera Initialized: ECB://192.168.1.110 @ 320x240
EZ-B v4 Camera Error: Unable to read data from the communication link: A connection attempt failed because the remote station did not properly respond after a period of time, or the established connection failed because the connected host did not respond.
camera disabled"
I've been trying to make changes in the sketch for a whole day, but haven't gotten any better results.
I give up and will continue with the normal WIFI function.
Has nobody tried anything like this?
Thank you very much for the help, if you have a tip to set up the picture that would be great?
