Quanta board package for the Casper project NL8K, with board number DANL8KMBAF0 at revision F, packed as a 1.17 MB RAR. The DA-prefix-plus-MB format is the standard Quanta motherboard numbering, and the last characters encode the PCB revision. Expect a schematic and possibly boardview data for tracing power rails, finding test points and checking shorts. Make sure the number silkscreened on the board, including revision F, matches before following component values or net names.
