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!

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. :)

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 *.drl

I 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.
