I recently purchased a couple of the ESP32-CAM modules hoping to add one to my 3D printer and possibly my Primo. I would recommend to purchase a name brand module such as WROVER or Ai-Tinker since I had a difficult time getting my knock-off version to work.
Mine came with the ESP32-CAM-MB with the USB to serial chip but I couldn’t get it to work so I ended up purchasing one of these.
The camera needs good lighting so I believe I’ll need to add a light. I was thinking of using one of the ring lights similar to what jeffeb3 posted here a while back.
I still need to design a housing when I have some free time.
