Powering my mirror?
-
the converter its self doesnt really get hot.(that i have noticed) it just the wire to the pi. and once it drops, it doesnt adjust anymore.
-
hm strange I mean I don’t know the cable size you use, but 5V 2A is pretty much nothing for any cable. Should not really get hot for sure
-
thats what i thought… i will continue to investigate and post back if i find anything.
-
2A is not nothing for a thin cable. What kind of cable are you using? If it is just a very thin one, it would also explain the huge voltage drop. Try using a thicker one.
I am running the Pi with a SSD with one of those very cheap china buck converters without any issues for 6 months now. -
Yep thats why I write I don’t know what siye of a cable you use ;)
but since I expected the cable to be very short (step down converter directly in front of the pi and the cable is probably open to all sides
VDE rules say you should use at least 0.5mm² up to 2.5A 2m
and at least 0.1mm² up to 1A 2mSo you should use 0.5mm² to be on the safe side.
0.25mm² should probably work aswell when you do not have long cables and do not stress the pi fully out to 2A ;)
But yes @MadScientist is right you should definetly not get below thisand keep in mind those values are for copper cables. If you use aluminium cables you obviously need thicker cables
