Hardware files for the Smoothieboard v2, and extension boards
This directory contains two kinds of boards:
- Ccecil designs are Git submodules pinned to specific revisions of their independent hardware repositories. Their descriptive directory names are stable here; upstream repository names and URLs remain unchanged. - Legacy designs are verbatim copies of folders from Smoothieboard2 master:extensions, captured at commit 52ab340de33180a975b25f856c161993488e6ace. They are ordinary tracked directories, not submodules, and do not update automatically when master changes.

Large MOSFET: common questions
How big is the Large MOSFET PCB?
The Large MOSFET measures 36 × 31 mm and is 1.6 mm thick.
How many components are on the Large MOSFET?
40 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Large MOSFET design files?
From the Smoothieware/Smoothieboard2 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Large MOSFET design in my own project?
The repository has no license, so all rights stay with Smoothieware. Use it as a reference, and ask the author before reusing the design.
