I am very interested in the ESP32-S2's camera port and the possibility of using it for a variety of MicroPython\CircuitPython projects. My hope is that the ESP32-S2 will the ability to do do things similiar to what is possible on the Raspberry Pi. Today there is no ESP32-S2 board available which exposes this port, and no camera modeles, but I wanted to understand the hardware capabilities to understand what might be possible and just as important, what is not.
