Dieter, you're right, linear regulators do waste a bunch of power. Just FYI, I took a *quick* look at the ADP1111 and it doesn't look to me like it's going to have enough power for the BB.
I'm using the TPS63061. It's a great part but the footprint isn't exactly prototype friendly. If you're interested, I have a small write-up and pic of my board here <http://andicelabs.com/beaglebone-power-bar/>. -Ron On Monday, November 11, 2013 3:22:39 PM UTC-6, Dieter Wirz wrote: > > Ron is perfectly right! > And where do you get cheap rechargeable batteries? > LIPO prices are going down > alcaline prices are going up > > Do you really want to invest time and money in last millennium > alcaline technology? > > 7805?
