From the project

The following repository documents my novice attempt at designing a microprocessor single-board computer. I had fun putting this design together, however without any prior experience it's left with many flaws which should be addressed if anyone would want to implement it again.

It's a KiCad project, however a single-page PDF of the schematic and gerber files are included, so KiCad is not required to preview it.
