Questions
How big is the HW4 PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HW4 use?
23 parts, built around the PIC32MX170F256B-I/SO, CP2102N-EK and AP7381-33V-A. 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 HW4 KiCad files?
From the klemensiten/ME433 repository on GitHub, at the commit this page was made from: the board is HW4/HW4.kicad_pcb and its schematic HW4/HW4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HW4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask klemensiten before reusing the design.
