another thing to beware of

i was working on a pico project with another guy, and he sourced some pico clones that do this

we then powered a full sized rpi off what was once the VBUS pin, what was once a direct connection to the micro-usb port of the pico

on this board, that pin is behind the anti back-feeding diode, which is only rated for 100mA
it popped the diode on one pico, and incured a permanent voltage drop on every other pico, causing under-voltage issues with all of the rpi's
