Assigning footprints

A footprint tells KiCAD the physical size and pad layout for each component on the PCB. Every symbol in your schematic needs one.

#Open the footprint assigner

Go to Tools → Assign Footprints (or click the footprint icon in the toolbar).
The left panel lists your component types. The right panel shows available footprints. The center panel shows your components.

#Assigning the Pico

#Assign the Pico footprint

Click RaspberryPi_Pico in the left panel.
In the search bar on the right, type RaspberryPi_Pico_Common_THT.
Double-click the result to assign it.

#Assigning diodes

#Assign 1N4148 to every diode

Click D_1N4148 (or whatever your diode symbol is named) in the left panel.
Hold Ctrl and click every diode in the center panel to select them all at once.
Search for Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal on the right.
Double-click to assign it to all selected diodes at once.

#Assigning switches

#Assign SW_MX_1u to every switch

Select all switch symbols (SW_Push) in the center panel.
Search for PCM_marbastlib-mx:SW_MX_1u on the right.
Double-click to assign.

#Assigning stabilizers

#Assign STAB_MX to every stabilizer

Select all stabilizer symbols in the center panel.
Search for PCM_marbastlib-mx:STAB_MX on the right.
Double-click to assign.

Click OK when all footprints are assigned.
