Everything works - computers and accessories

Programming the board was a bit difficult. To turn it on, 5V was applied to the 5V line rather than the Vin line. (3.3v to 3.3v line didn't work either). It appears that the reset pin is not broken, so programming via the serial port will require a manual reset of the board. Using the CameraWebServer example thumbnail, the camera should have been defined as CAMERA_MODEL_AI_THINKER and not the default CAMERA_MODEL_WROVER_KIT. The camera has a very noticeable rolling shutter, but I think it's a…

Pros
  • Easy to read control panel
Cons
  • Neutral

Never worked properly

Numerous problems. Tried to get it working when I got it and put the device off until trying again after picking up one of the Bitluni ESP32 CAM programming boards. It didn't work - while it worked for him, I thought maybe the power supply was weak, so I went back to my breadboard setup. The device draws a lot of power, I ended up not using the power of the serial converter by putting a big cap on the power supply and using a desktop power supply to get the 5v input voltage down to about 5.3v 3

Pros
  • This is amazing
Cons
  • Some bugs
