I had an arduino giga r1 for the past 5 months now, i've been powering it with usb-c from my pc, I have also been using the giga display shield. Everything worked fine until last week when i powered on my pc and the giga R1 was dead, buzzing sound warm-ish SMT32, otherwise no visible damages after deep inspection, no parts getting hot, and a 10 ohm resistance between the 3.3v and gnd lines, any idea what could cause this short?
Did check that resistance with the probes reversed and not reversed?
Was ir a steady 10 ohms in both directions?
