Foxconn schematic for a board with the project name STAR, revision R1.1, compressed into an 851 KB RAR archive. The name does not identify the finished device or its brand beyond the Foxconn design code. Inside you should find circuit diagrams used to follow power rails, check the sequencing of enable signals and locate components linked to a short or missing voltage. Because project names like STAR can cover several variants, match the revision and code printed on the board before using the drawings for repair.
