Better safe than sorry and regret later.....
I'm more inclined to blame the connections on the ends of those cables.Heater wrote: ↑Wed Oct 10, 2018 10:23 pmThe happiest Pi I have is run from a 5v supply that can deliver 4 amps.
But this supply can be tweaked up and down a bit by winding a trim pot.
Turns out the Pi is happiest when the supply is outputting 5.3 volts or so.
It amazing how much voltage can be lost through short lengths of cheap skinny USB cables.
I'm skeptical about that particular set of requirements. I tested a Pi0+3.5" display (GPIO mounted) and the whole thing drew less than 250mA, and most of the time it ran at about 185mA. The B+ is, IIRC, spec'd for and polyfused at 1.1A, so a 1.5A PSU is mild overkill. An A+ should run on more like 500mA, even under load. The Pi0, Pi0W, and A+ all lack the rather power hungry LAN chip, and with only one USB port really don't need enough power to output more than 500mA, max. and probably a good deal less in most cases.
Most kit resellers package their own PSU, not the official PSU.
The Canakit PSU is okay (I've had one), but the official Raspberry Pi Universal Power Supply is better. I've seen the Canakit PSU dip a little below 5V under load, but not enough to cause a low voltage warning (at least mine didn't).soydepr wrote: ↑Thu Oct 11, 2018 11:42 pmattached!!!

Under-voltage detected! (0x00050005) / Voltage normalised (0x00000000)
And are you using as a wire?
In future, rather than ressurecting an old thread, just start a new one.ebolisa wrote: ↑Wed Mar 06, 2019 9:41 amSorry for resurrecting this post but I've a doubt...
I'm running a B+ with updated debian stretch plugged in the extension board seen here: https://www.kubii.es/tarjetas-de-extens ... 13346.html
The 5V is fed via pins 2 & 4 as per the extension's board design (so, not through the USB connector).
The PS used is a 5V 3A as shown here: https://www.meanwell.co.uk/dr-30-5.html
However, I'm still getting the following messagesUnder-voltage detected! (0x00050005) / Voltage normalised (0x00000000)
So, I'm suspecting that the Pi's voltage sensing is done within the USB circuitry otherwise, I cannot understand the message.
Any help/ideas is appreciated.
