http://x.x.x.x/rgb Captures an image and converts to RGB data (will not work with the highest
resolution images as there is not enough memory)
GPIO PINS:
The main io pins available for general use are 13 and 12 (12 must not be high at boot)
14, 2 & 15 should also be available if you are not using the SD Card
You can use 1 and 3 if you do not use Serial
More info: https://randomnerdtutorials.com/esp32-cam-ai-thinker-pinout/
BTW-You can use an MCP23017 io expander chip on pins 12 and 13 to give you 16 general purpose gpio pins
Note: If using an sd card you this will normally stop you using pins 12, 13 and the led on 4
but if you put it in to 1-bit mode it allows you to carry on using these pins
The command to use 1-bit mode in the Arduino IDE is: SD_MMC.begin("/sdcard", true)
see an example of its use here: https://github.com/alanesq/esp32cam-demo
pin 16 is used for psram but you may get away with using it as input for a button etc.?

I have heard reports of these modules getting very warm when in use although I have not experienced this myself, I suspect it may be when streaming video for long periods? May be worth bearing in mind.
