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?

    Damn, I typed a long response here and lemmy ate it.

    Anyway: From a “preliminary” data sheet found from a quick earch, it looks like the OV2640 in particular uses a 10-bit-wide, optionally 8-bits, single-ended version of DVP. It’s probably not too impractical to multiplex that.

    I’d guess it’d be easier to give each camera its own ESP32 though since they’re pretty cheap. Or if you can do the recognition on an inexpensive NXP/STM/whatever µc.
