So, I was lying in bed last night (because this is the sort of stuff I think about when I can't sleep) and I hopped on the old googlemachine and found the ESP32-CAM module, see here: https://www.dfrobot.com/product-1879.html The basic gist here is that it's an ESP32-S2 mated to an OV2640 camera (2MP). Now, that's not super interesting, until you look at the ESP32-S2-MINI-1: https://www.espressif.com/sites/default/files/documentation/esp32-s2-mini-1_esp32-s2-mini-1u_datasheet_en.pdf It's a module only slightly bigger (20mm x 15.4mm x 2.4mm) as the ESP-12S (16mm x 17mm x 3mm), which means we might be able to fit it. Now the one thing I haven't done a pinout mapping study. As in, is it possible, with a custom board fab, to add a camera without losing some other functionality? I've ordered one of the modules this morning so I can mess with the code and get the video streaming working. Code will be up on GitHub. Anyone interested in playing?
