 The aim of this page is to give the community the possibility to publish improved layouts of MBHP modules. The original layouts by TK are mostly quick solutions with focus on "first-time-right", and therefore not very well optimized with regard to area size or number of bridges.  The aim of this page is to give the community the possibility to publish improved layouts of MBHP modules.

-   * never use a cracked version of Eagle. Not only that this is illegal, but such version also corrupt the .brd files (they cannot be opened with the freeware version anymore)+   * It is against the law to use any pirated/cracked software, and this is absolutely not to be done here. If you have a registered copy of Eagle, or a freeware/Eagle Light version, go right ahead. Cracked software is not only illegal, but  will also corrupt the .brd files (they cannot be opened with the freeware version anymore).    
 +      * Consider Kicad if you need a larger layout. It is open source and free to download from [[http://kicad.sourceforge.net/]]
