I am trying to setup the new rpi3B+ with the new volumio image. : 2.411
I am useing an 8 GByte sd card. and no dac yet.
I had very briefly the volumio hotspot, after only 20 sec. or so, it is gone and does not come back.
So I cant setup the new system or make a connection with my home wifi network.
I have tried the psu with the rpi 3B setup. and that works. So indeed the 3B+ needs more power.
my 3B psu also feeds a 256GB ssd but i tested te new 3B+ without the ssd.
My guess is with the SSD and a good dac shield it consumes about 3,5 to 4 amps.
The good things the new 3B+ starts very fast.
