ESP32 with multiple cameras

  • Thanks to everyone for the all helpful responses.

    Connecting each camera to its own ESP32, which process the data and sends only necessary information to the main ESP32, I think is a cool idea.

    I plan to use this Schamatic as a guide for building the ESP32 cam parts on my pcb, although I'm sure I'll be using a slightly newer ESP32: https://github.com/SeeedDocument/forum_doc/blob/master/reg/ESP32_CAM_V1.6.pdf

    It seems that the PINS U0TXD and U0RXD are free. Can I use these to connect them to the main ESP32 via UART or is there a better way to connect all ESP32 cams to the main ESP32?

    And there is one more question. How can I program the ESP32 of the cams? The main ESP32 will be connected to a Micro-B SMD USB connector. Do I need another one for each ESP32 (for the cams) or is it possible to program all ESP32 via the same USB connector?

    ESP32 with multiple cameras

    I want to connect five OV2640 cameras via FPC to an ESP32 on a custom PCB. Is this generally possible and does the ESP32 have enough power for this or do I need an ESP32 for each camera? The frames per second are not so important as the cameras will be used as QR code scanners. Which components allow to run so many cameras with one ESP32?
