Hi guys.
I made this https://www.instructables.com/id/Arduino-Powered-Headdress/
the elettronics works at 5volts and drain max 4 amp.
My needs is a battery pack easily rechargable and smaller as possible'.
I would like to cahrge it from usb
can you suggert me a setup?
this is what Ia m thinking about right now
USB 5v --> step up to 9V -- battery charger protection --> 2 x 18650 in series---- > step down regulator to 5v --> to hat elettronica board
it seems to me overcomplicated , is there a simpler solution ?
thank you
Andrea
