Talk:Reducing power consumption of a raspberry Pi
Re: Eliminating the 12V-5V converter in your low-power Raspberry Pi implementation
I have found your page most helpful in my own hack. I have duplicated your work and it works; Thank you!
I realized that VDD_BAT merely needs to be tied to 3.3V for it to work. There is no need to include a second 12V to 5V converter specifically for VDD_BAT. I have verified this with my setup and it led to further power saving (1.524W down to 1.44W at idle). Please consider trying it on your own Raspberry Pi too!
