looking for mh-et live esp32 minikit schematics

[danny@cs.huji.ac.il]

Hi,
I have the some mh-et live esp32 minikit , and a very similar Wemos mini32, both have 'similar' pin out,
I am trying to power them not via the mini usb, but using either the 3.3 pin, or the vnc pin,
with different results, so does any one know how to do this correctly? - i'm a programmer, with some very basic
knowledge in electronics.

thanks,
danny
