Artifacts
There is a shorter manual for EasyMini which is available in
html and
pdf formats.
Thanks to Bryan Duke, there's also a 3d model of EasyMini available on
Thingiverse.
The hardware design files can be found on git.gag.com
in the project hw/easymini.
For those who don't have ready access to the gEDA suite, here are pdf snapshots
of the files for production PCB version 1.0 in more easily readable form.
