Overview
Nandpi is an open-source printed circuit board by neggles, from the neggles/flashpi repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 65 × 56.5 mm with 16 parts on 10 nets, routed with 94 tracks and 24 vias.
Its parts include 4 capacitors, 2 switches and 1 connector.

Building
Simply call make in the top-top level directory. The build directory will then contain:
- the main board
- zipped gerbers for the boards you can directly use for manufacturing
- zipped gerbers and SMT assembly BOM/position files for JLCPCB's SMT assembly service for the single-board version.
Makefile uses Jan Mrázek's KiKit, which I cannot recommend enough, and therefore has to be available on your system.
Jan's jlcparts app was also extremely useful in narrowing down part choices based on what JLCPCB have available.
IMPORTANT NOTE: If you give JLCPCB these files as-is, please verify the orientation of every part before submitting.

Questions
How big is the Nandpi PCB?
It measures 65 × 56.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nandpi use?
16 parts. 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 Nandpi KiCad files?
From the neggles/flashpi repository on GitHub, at the commit this page was made from: the board is nandpi/nandpi.kicad_pcb and its schematic flashpi/flashpi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nandpi design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
