wondering too much with this..
is there maybe someone who can tell me which way is preffered and why..
im usually taking low-current 3.3v applications out of the 3.3 volts onboard regulators on some of the ESP boards out there.
then a way to route the ground , which could be 1 of 2 :
1) back to the same esp board , that provided the 3.3v
2) back to the more general ground of the (5V) PSU
Thank you
