Engineering revision R0.2 schematic for the Compal LA-1931 board, stored in a 1.22 MB RAR archive. This is the earliest of the LA-1931 versions catalogued here, so it may differ noticeably from retail boards, and a later revision is preferable when available. The name names no brand or chipset; LA- is Compal's ODM numbering. It remains handy for understanding the power tree, the signal routing and the regulator circuits. Extract with WinRAR or 7-Zip and check the revision on the PCB.
