Warranty
Thanks to the seller, everything works, modules already with test firmware. To use, connect the board via ftdi converter: gnd-> gnd, + 3.3-> pow, rx-> uot, tx-> uor; from arduino, open the port monitor at 115200 speed and follow the instructions. Important! Feed extra good power + 5 v-> 5 v, without it the program is fixated with the message "brownout detector was triggered". Detailed manuals look for in google by the phrase "ESP32-CAM video streaming"
