I have MBR0520 Schottky Diodes available for Nano V3 repair

FYI, for anyone that has a burnt diode on their Arduino Nano V3, I currently have a bunch of them available.
I'll sell them for a couple of bucks, just enough to cover cost & postage.
let me know if interested

You might want to explain a bit more - how would one know if a damaged board
could be fixed with this diode? What circumstances lead to the failure?
