Questions
How big is the HE16 PCB?
It measures 75.2 × 75.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HE16 use?
103 parts, built around the W25Q32JVSSIQ, MT9102ET, AT32F405RCT7 and TLV75733PDBV. 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 HE16 KiCad files?
From the peppapighs/HE16 repository on GitHub, at the commit this page was made from: the board is HE16/HE16.kicad_pcb and its schematic HE16/HE16.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HE16 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).
