Ordered Orange Pi Win Plus from official Orange Pi store, it came with bundled PSU.
I always get different errors when latest (by post date) linux Armbian starts and sometimes it starts correctly.
I read this forum carefully and found out this is shitty PSU symptoms, so I took 20 Amps ampermeter and short-circuit PSU through it for 2 seconds, display stopped counting at 1.42 Amps. It is below specs where literally 2 Amps is required!
Besides this I measured voltage and current near board PSU outlet, I got max current it eats through boot process is 0.54 Amps and voltage falls max to 5.32 Volts. Seems like PSU must fit this board but I still get that low power issues. Physics laws are wrong or what?)
Someone maybe can tell me voltage should not be lower than X so board will work good. X = ?
My multimeter looks like this:
