Hi i have Node MCU 0.9 and i need to power it up with battery
But it seems as if it doesnt takes more than 5v.
can i connect 9v ?
Please see the picture and you ll see 5v on pin where VIN shuold be mentioned as per internet blogs. While this board has 5v or 3.3 v. Can i connect battery to this 5v ? and if 9v will work or i should try any thing more than 9v
