Questions
How big is the HPM5E31 PCB?
It measures 42.7 × 52 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HPM5E31 use?
225 parts, built around the HPM5E31IGN1, TJA1042TK/3/1, RTL8201F-VB-CG and RY3430. 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 HPM5E31 KiCad files?
From the HNUST-Dust/HPM5E repository on GitHub, at the commit this page was made from: the board is hardware/HPM5E31.kicad_pcb and its schematic hardware/HPM5E31.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HPM5E31 design in my own project?
Its repository states no licence, so its author keeps all rights: ask HNUST-Dust before reusing the design.
