Eggbot
The “original” EggBot was designed by Evil Mad Scientist Labratory. They now have 3 different versions, and a comparison guide for all three.
- The HW Design is not on GitHub, but in their wiki: Hardware reference design. It seems to be for the “Deluxe” version, the “Pro” version has no HW details available?
