Those are just links, trivial to repair, but that's not the issue: If those have blown then it's all but certain that something else did as well. The good news is that the damaged circuit is easily recognisable as your basic SMPS, a very common field of electronics that any engineer or even decently skilled hobbyist can repair, and it's quite unlikely that ...
Does any one know what components have been damaged?
They look like 0 Ohm SMT (surface mount) resistors.
I can't tell the physical package size but they look relatively large.
I cant tell the power rating. You'd have to guess and hope for the best.
And where would I get replacements from?
Any electronics supply business. For example CPC
You could also ...
So after asking elsewhere I got half of my question answered. The reason the boards exploded was because the polarity of output was backwards. For some reason Gridseed supply power cables with the typical colours of red for live and white for ground reversed!
My solution was to swap the white and red wires over and I got no more explosions.
Does any one ...
Ok, I found the solution here and here:
You have to enable SLUB debugging for your linux kernel. Therefore you have to edit your linux kernel command line:
sudo nano /boot/cmdline.txt
Add the following code at the end of the first line (on the same line as the other text, don't add new line!).
Save the file then reboot your Raspberry Pi.
