Dude – this is getting old – said it all before.

Unknown Schematic Symbols

Newbie here. Hello, I found a schematic online and want to create a pcb design, however I don´t know what the circled symbols mean or how to find them on Kicad. Do they have standard footprints? I was thinking about changing the chest1 symbol for a header pin. [Captura de tela 2023-01-04 184216] Could anyone tell me what their names are on Kicad? Thanks a lot
