Sorry, accidentally the post received a negative rating. Should've been +8 points. The only thing to mention: Why so late?! The v3.0 schematics are available since 1st of Sep. -- and you release them now?

So many questions are answered instantly by looking into it...


It seems that the pdf files are corrupted in some way, I couldn't open them correctly especially the first one which is almost empty. The second one has correct schematics, but an empty first page.
Perhaps a specific font that is not available on regular pdf readers..



In Linux it works. With windows 7 & Adobe Reader 11 it did not work for me.  Post time Oct 22, 2015 02:19

I use Foxit Reader to view the pdf, and it can work well.


Whatever the reader is, it should be readable, especially with Adobe reader, especially if the product is meant to be sold.

The lastest schematic and pcb layout

Hi John,

Thank you for the update, there are no notes about any changes, but the date of the drawing is now 21 December 2015.
Did you make any changes to the schematic of the base board?
Maybe changes to the USB3.0 connector?

Please advise


I am not able to open brd file in eagle or kicad.

Eagle error:
Loading xxxxxxxxxxxxxxxxxxx/LMK_Guitar_Base_Board_Rev.B_V1R3_20151101.brd ...


line 1, column 1: Start tag expected.

Kicad errors:
Error loading board.
IO_ERROR: Unknown file type
from C:/Jenkins/workspace/windows-kicad-msys2-stable/src/kicad-4.0/pcbnew/legacy_plugin.cpp : checkVersion() : line 571

When I select eagle brd file format I am getting:
Error loading board.
IO_ERROR: C:\Users\grzegorz\Desktop\lemaker\LMK_Guitar_Base_Board_Rev.B_V1R3_20151101.brd(1): expected <

Can you update that file please?

Thank you and have a nice day.
