Questions
How big is the Chicker PCB?
It measures 152.1 × 80.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Chicker use?
195 parts, built around the FGH50T65SQD-F155, LMV321IDBVR, TS-1187A-B-A-B and AMS1117-3.3. 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 Chicker KiCad files?
From the sfunderbots/Electrical repository on GitHub, at the commit this page was made from: the board is Chicker/Project Files/chicker.kicad_pcb and its schematic BasePlate/BasePlate.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chicker design in my own project?
Its repository states no licence, so its author keeps all rights: ask sfunderbots before reusing the design.
