Which revision of LA-E581P do I have?
Files for this board mention Rev 0.3 and Rev 2A. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
