I am using an ATX SMPS to power my Orange Pi Plus 2 via 5V supply. It worked fine for a couple of days without problem until yesterday. I happend to connect my audio amplifier TPA3116 which worked fine. After which when i was switching some cables i happend to short the 12V supply. The smps immediately shut itself down. Now i removed the short and disconnect the audio amplifier from 12V supply.
After this when i started the orange pi there was no more any indication. I wanted to know that if the 12V short let to an inrush current spike at the 5V power section. If any one on this forum is aware of fuses present on the orange pi board.
