To program the board, I userd jumper to jump GPIO0 with GND pin next to it.

old, obsolete problems

It seems that my module is usually known as AI thinker variant. It has terrible picture which starts with huge green bias.

It also doesn't work for me in resolutions below 1024x768 (in current esp32 example as of 2019-08-02).

Plugging it into external 5V power supply did not helped much.

To solve green tint, I just left esp32cam module plugged in whole day and night. I guess that image sensor got discharged during night, but next day picture was fine.

Problem with image resolution was fixed by updating to more recent version of ESP32 support for Arduino (as of 2020-04-20 it works fine)
