Dear All, good morning.
I am actually creating a PBC of a schema.
http://www.hello-web.net/temp/PowerCell.pdf
I have a big doubt on the Switching regulator, there is two groung , GND and GND1
Which is the difference?
The GND is the ground of the batterie (3.7V)and should be connected to all GND?
the GND1 is the ground of the output (5V) and should be connected to all GND1 AND NOT to the GND?
If GND and GND1 has to be connected, is true that it have to be connected with a very small wire?
Thank
