FTDI helper for the future. With FT230X, blinky lights and USB-C! Also potentially the tinyest USB-C to Serial adapter in the world. 😃
Got a smaller USB-C to serial adapter? Please send me a link!

Create Gerber files
After you exported the gerber and drill friles from KiCAD to a subdir like gerber you can use the gerbolyze tool or the [webservice][gerbolyze_web] to add the artwork to it.
Install gerbolyze with pipsi:
pipsi install gerbolyzeI already created the template with gerbolyze render bottom gerber preview.png and added the artwork to the correct places. To add the results to the gerber files use:
gerbolyze vectorize bottom gerber gerber_art preview_002.pngThis will create the needed gerber files including the artwork in a directory called gerber_art.
To create a ZIP file with the needed gerber files for a PCB fab:
cd gerber_artzip darling.zip *.gbr *.drlI recommend JLCPCB. It's the cheapest way to get the PCBs and they offer decent quality. If you want purple PCBs you can also use OSHPark. If you want it faster and you're in Germany I uploaded it to Aisler to.
