Questions
How big is the HornSystem PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.61 mm thick.
What parts does the HornSystem use?
233 parts, built around the STM32F103RCT6, SN65HVD230D, ADA4522-1AR and FT230XS-R. 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 HornSystem KiCad files?
From the cristobalcuevas/PCB-Designs repository on GitHub, at the commit this page was made from: the board is HornSystem/MainBoard/MainBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HornSystem design in my own project?
Its repository states no licence, so its author keeps all rights: ask cristobalcuevas before reusing the design.
