LPC313x - ha7ilm/opendous GitHub Wiki
This board has been prototyped but is not very useful.
The LPC313x-DIY has limited functionality as it is a 2-layer single-sided components board made to 8mil-8mil-20mil (trace-clearance-minimum_drill) specification.
The relevant KiCAD design files can be found through SVN in the /Abandoned_Designs/LPC313x-DIY/
directory.
A PCB of this design can be purchased at cost through BatchPCB.
