KiCad Files
The first design used EAGLE 6. I converted the EAGLE files into KiCad 5. This reduced the time to re-capture the schematic but it also caused a mess with the libraries and silk screens.

Questions
How big is the Reflow Control Board Rev 2 PCB?
It measures 74 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Reflow Control Board Rev 2 use?
62 parts, built around the ATMEGA32U4-AU and DS3231MZ/V+. 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 Reflow Control Board Rev 2 KiCad files?
From the baldengineer/Open-Vapors repository on GitHub, at the commit this page was made from: the board is KiCad/Reflow Control Board Rev 2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Reflow Control Board Rev 2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
