UART pins! That is such a good idea!! I need to get some of this stuff and make some stick-on connectors so I don't have to solder pins whenever I need a UART for 30 seconds to unbrick a router or something

Springy pogo pins are what you want.

Hold them on with one hand while you type a few commands over the serial connection with the other.

If you have more in depth debugging to do, get a 'helping hand' to hold it in place.
