As an EE
you should know the reason. When you use a boost converter to increase the
nominal 5V, you reduce the total current available AND increase chip count
on the board.? The Pi foundation has always stated phone chargers were
not acceptable power sources for any pi product.? They are designed to
charge 3.7V to 4.2V phone batteries.? They may put out 3 amps, but in
doing so, their voltage drops.? The voltage drop is t critical since
the voltage is reduced and regulated to charge the phones
Having a BSEE,
I've always wondered why the developers of this Ri5 have a need for the
extra +.1v on the 5v input, that the other versions are not critical of.
I'm thinking it's to ensure there is ample current available. 5v is
ubiquitous in the computer world but the Rpi5 is wanting to need that extra
.1 volts. Seems like this could be handled by the circuitry instead of the
power source.?
