LATEST NEWS!!!
There is now a very cheap motherboard available for the esp32cam which make it as easy to use as any other esp development board.
Search eBay for "esp32cam mb" - see http://www.hpcba.com/en/latest/source/DevelopmentBoard/HK-ESP32-CAM-MB.html
It looks like older esp32cam modules the reset button has no effect on them (I am guessing this is a feature on newer modules) so on
these you have to plug the USB in whilst holding the program button to upload a sketch also I find I have to use the lowest upload
speed or it fails to upload. The wifi is very poor whilst in the motherboard (I find this happens if you have something near the antenna on the esp32cam modules) but if I rest my thumb above the antenna I find the signal works great).
It looks like the esp32cam suplied with them are not standard and have one of the GND pins modified to act as a reset pin?
So on esp32cam modules without this feature you have to plug the USB in whilst holding the program button to upload a sketch
also I find I have to use the lowest upload speed or it fails to upload. The wifi is very poor whilst in the motherboard (I find this happens if you have something near the antenna on the esp32cam modules) but if I rest my thumb above the antenna I find the signal works great).
So they are far from perfect but still for the price I think well worth having.

This can be used as a starting point sketch for projects using the esp32cam development board,
