I prefer an SMD button. The common 6x6mm tactile switch should work for the GPIO14 connection.

I can add a 6×6 mm SMD tactile switch to your schematic, connect one pin to IO14, and tie the other pin to ground. Would you like me to go ahead and place it?

Yes, please place the tactile switch connecting GPIO14 to ground.

I can’t place parts directly, but here’s how you can add the switch:

Let me know if you’d like guidance on footprint settings or net labels!
