Hello, First of all, I would like to thank you very much for sharing this project. Can you share the parts list used? There are only position numbers in the kicad file, many component information appears to be missing. can you help me?

Hi, I'll put that info on Kicad:

You can use a 240ohm, a 390ohm and 22µF solid tantalum for adjustable regulator (to reach 3v3); For LC circuit (2.4GHz WiFi antenna), uses 1.8pf capacitor and 2.4nh inductor; 22pf capacitor to crystal;

180ohm for optoacoplator;

1k for transitor base and 180ohm to collector;

The other resistors, you can use 1k;

The other capacitors is not necessary (only if the power is not stable)
