Battery connected to GPIO

Mon Jan 26, 2015 9:42 pm

Hi all,

Firstly I know this isn't recommended and could damage my board but, is possible to power the Pi using a 3.7v battery connected directly directly to the gpio pins without any additional hardware?

Thanks in advance!

i know the usb devices will refuse to work on 3.7 volts

i'm not sure how well the cpu would run on 3.7

but there is another route that i have used on my pi, https://www.sparkfun.com/products/11231

this will boost the 3.7 up to 5v, so you can just power it from 5v normally and everything will work fine
