Hello,
I have a rpi 3b+ with rasbian buster installed. I'm using orico 5V 3A charger as a power supply. When raspberry is turned on, undervoltage yellow blizzard icon is displayed. Which is the right official PSU for this board? I found that there are a few models of official power supply:
No 1. T5875DV
No 2. T6090DV (same parametres as number 1)
No 3. T6716DV
No 4. T6712DV (same parameters as number 3)
