Questions
How big is the Nano5 PCB?
It measures 100 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nano5 use?
187 parts, built around the ATMEGA328P-AU, ESP-12E, ST485EBDR and LM358. 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 Nano5 KiCad files?
From the RJLABS/flatcracker repository on GitHub, at the commit this page was made from: the board is HW/NANO5/Nano5/Nano5.kicad_pcb and its schematic HW/NANO5/Nano5/Nano5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nano5 design in my own project?
Its repository publishes it under the AGPL-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).
