Questions
How big is the Hpe mini PCB?
It measures 87 × 106 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Hpe mini use?
172 parts, built around the MPXHZ6400AC6T1, 1N4148WS, AO3400A and B5819W. 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 Hpe mini KiCad files?
From the D0kRay/hpe-mini repository on GitHub, at the commit this page was made from: the board is hpe_mini.kicad_pcb and its schematic DOUBLE_PU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hpe mini design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
