Revision 2.1 layout file for the MSI MS-7199 desktop mainboard, a boardview packed in a 346 KB zip archive. After extraction it loads in boardview software such as OpenBoardView or FlexBV, where you can search parts by reference, highlight nets and check pin connections while measuring. It is useful for locating components around a failed regulator or tracing a signal between chips. Neighbouring revisions 2.0 and 2.2 are close but not identical, so confirm the revision marking on the PCB first.
