1) Just out of curiosity, where do you get a source of 3.3V?mattvenn wrote:I can confirm that putting 3.3 and 5v into the pi works.
exactly, and its very educational to try to do something that is supposedly impossible.a guy made a weather balloon using a RPi running with only 3.3v powering it.
What it was designed for, and what it will happily do anyway, are two different things. Just connect the incoming 3.3V to the 3.3 and 5V lines (e.g. on the GPIO header) and the Pi will boot and run normally. That includes the LAN on a model B, HDMI and at least some USB devices. I do this all the time.boyoh wrote:This question is being answered with to many IFFs or BUTTs
The Pi was designed to to work with a regulated 5vdc in/put
The on board regulator stepped the 5v down to give you
3.3v for the GPIO in/puts & out/puts to interface with your
Projects. Back feeding the Pi causes to many problems.
The Pi was designed to learn programming and electronics.
So use the Pi within It's designed parameters
Although I generally do remove the 3.3V regulator, you don't have to. Doing so reduces current consumption a little, and the weight by a tiny amount, but unless these are important (which they are for me) then don't bother.RoboJ1M wrote:Yes you can apparently.
It involves removing the 5v regulator, fooling the power pin on the bcm and voiding your warrantee, but I did read a how to do it.
I'm looking at solar power and it's one of the ways to cut down power consumption. You can even run USB peripherals if they will run of of 3.3v
I'll see if I can find the guide link.
