Questions
How big is the Feeder PCB?
It measures 36.5 × 36.5 mm and has 4 copper layers, 1.63 mm thick.
What parts does the Feeder use?
54 parts, built around the HMHA2801A, NCP12700ADN, BAS20HT1G and PA2467NL. 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 Feeder KiCad files?
From the owntech-foundation/Feeder repository on GitHub, at the commit this page was made from: the board is KiCAD_files/Feeder.kicad_pcb and its schematic KiCAD_files/Feeder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Feeder design in my own project?
Its repository states no licence, so its author keeps all rights: ask owntech-foundation before reusing the design.
