This is a really stupid question, but forgive me- I’m new both to KiCad and to electronics in general (though I have built a number of kits and other synthDIY-related projects).
I’ve created a custom component for my eeschema schematic and I can’t work out what pin type to set for GND (ground) pins. After looking at some KiCsd tutorials, I’ve made them all ‘Power Outputs’, but this doesn’t seem right. Also, when I’ve checked my schematic using the ‘Perform electric rules check’, it flags up errors for all my ground pins.
In other places on the interwebs your help request would be deliberately ignored, as you don’t provide sufficient information to give a definite answer.
Or to be more blunt: “where’s your logfile / error messages”
I ran into similar questions. As was mentioned in other responses, I set the pin type to “power input”, I linked it to a GND module and then elsewhere on the schematic, I added a separate PWR_FLAG also connected to GND. This effectively creates the GND net and marks it so the diagnostic errors don’t appear. You would do the same for your input voltage side only instead of GND, you would use +5V or something more appropriate to your circuit.
I make a separate sub-sheet with all power nets I use and attach POWER_FLAG to them. Then I tuck it in the corner and forget. This way I can reuse it in other projects, and flags don’t show on my schematics.
