Second of four RAR volumes in a collection labelled, in Russian, schematics and boardviews, sized 1.76 GB. The title carries no device names, so the exact range of boards inside remains unknown until the set is extracted. Keep part1 through part4 together and start unpacking from the first volume using WinRAR or 7-Zip. Collections like this usually mix PDF schematics with boardview formats like BRD, FZ or CAD, which need a dedicated viewer. Always match board revision before relying on any file.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @opendatasheet. Enginerys does not host this file.
