Questions
How big is the AutoFeeder PCB?
It measures 156.6 × 125.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AutoFeeder use?
58 parts, built around the MK20DX128VFT5, DRV8835DSS, TC1262-3.3VDB and BC847. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AutoFeeder KiCad files?
From the ErichStyger/McuOpenPnP_Machine repository on GitHub, at the commit this page was made from: the board is KiCAD/AutoFeeder/AutoFeeder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AutoFeeder design in my own project?
Its repository states no licence, so its author keeps all rights: ask ErichStyger before reusing the design.
