Great news, though very sorry to hear about the continuing positive test.
The WinterHill project has a problem as the Murata OKR-T/3-W12-C switching regulators are not in stock at the moment and have silly lead times.

The temporary solution is to construct 5.1V, 3.3V and 1.1V supplies external to the board and feed them in via the header highlighted where there is also access to the input supply and ground. Those could be Ebay modules or simple switchers with 3A capability.

Edit - I see Digikey have the 6A versions currently in stock, Part Number 811-2179-ND a little excessive but they are theoretically drop in replacements.
