Boardview for the iMac 27 inch model A1419, EMC 2546, logic board 820-3299, supplied in BRD format inside a 209 KB RAR archive. Apple logic boards use the 820-xxxx numbering printed on the PCB, which must match before using the layout. BRD files open in OpenBoardView, FlexBV and similar tools, showing component locations and net connections. Repairers use it to find test points for power rails, locate a shorted capacitor and follow signals between the SMC, power stages and GPU area.
