See Octopart for a detailed list with links. With current prices this totals to ~4.50€ just for parts excluding costs for the PCB manufacturing. If you need a PCB, just ask. I have lots of them. :)
Schematics
Create Gerber files
Export the gerber and drill files from KiCAD to a subdir like gerber. To create a ZIP file with the needed gerber files for a PCB fab:
cd gerber
zip darling.zip *.gbr *.drlI recommend JLCPCB. It's the cheapest way to get the PCBs and they offer decent quality. You can directly order it at PCBWay. They've got some nice matte black PCBs! If you want purple PCBs you can also use OSHPark. If you want it faster and you're in Germany/EU I uploaded it to Aisler to.

Questions
How big is the Darling PCB?
It measures 24 × 14 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Darling use?
21 parts, built around the FT230XQ-R. 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 Darling KiCad files?
From the XenGi/darling repository on GitHub, at the commit this page was made from: the board is darling.kicad_pcb and its schematic darling.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Darling 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).
