- What is the difference between footprints and symbols?
- How to connect a wire to the PCB?
- How to get a downloaded symbol, footprint or full library into KiCad version 5?
Plus: why is this lib not already in your system? It is shipped with KiCad 5. My guess is you did not install libs. My guess: I installed KiCad 5 (under Linux) but there are no libraries. (The default option for sym lib table setup is disabled) Or I had KiCad 4 installed previosly. Now i updated to v5. Now i have some problems with the library setup
