3x powersupply for rpi

[fboe]

Hi

That will be a tricky mod, because you have to disable the onboard regulator to power it with 3 x eksternal power, and then enable it with several jumpers to power it with USB.

Hi all
I intend to contact for customize Pi with low noise LT3045 on board. But minimum order size must be 1000.
Do you attend this group buy?

I'm in if the price is not too bad, do you have a quote yet

Hi,

According to topic opening, a small but probebly noticable tweak would be feeding a 5V via GPIO 2 and 6.
Can I use my regular standard rpi wall supply for this?

Thanks,
Dror

I share My setup

Just change LT1084 by LT1963 x3 supply for 3xLT3045 to pi3x4wires

What are the 1963 config?
7.5v 5v 3.3v ?

Nice share. thank you!
But again I'm asking if a regular standard rpi power supply could be used for the 2,6 GPIO pins tweak. I would try it myself if I wasn't afraid of damaging the rpi/DAC
