Boardview for the Lenovo JS574 mainboard, LCFC NM-E401 revision 1.0, provided in BDV and TVW formats within a RAR archive. TVW files open in Teboview, while BDV works in common boardview viewers. The layout helps locate components, measure test points, follow power rails and pin down shorts on this LCFC-designed board. NM-prefixed numbers are LCFC codes, printed on the PCB near the edge. Check that number and revision on your board before using the placement data.
