SlushEngine Model:X

This repository contains the hardware design files for the SlusheEngine. The current design is created on Kicad (BZR 5744). If you wish to contribute to the SlusheEngine project please contact Reiner at info at roboteurs dot com.

If you want to get going on your own project using the SlushEngine please fork it and have fun!
