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: github.com/SeeedDocument/…/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?
