What’s the best way to connect to 2.54mm breakout holes without a header?
Asked by uN3xample42
I'm looking for a quick and clean way to connect to 2.54mm breakout holes that don't have headers soldered in. I've tried using aluminum foil wrapped around the pins of a header to make a connection, but I'd prefer a more reliable solder-less option. Any suggestions?

If you're designing your own PCB, consider staggering the holes slightly to make it easier for a male pin-header to fit snugly. I found that helpful when designing mine! Also, heating up the male header could make it more flexible to fit into tighter spaces.

Pogo pins are definitely worth considering for a temporary connection. They can connect nicely without needing any headers, and they're pretty easy to use when you need something that’s not permanent.

Check out these connectors from Adafruit! They can fit well into the 2.54mm holes and provide a good connection without needing a header soldered.
uTechieLlama87: But just a heads up, those may not be super reliable because they’re meant to be pressed in permanently, not for temporary connections.

uPogoPro56: Totally agree! I actually have a programming header project coming up that I plan to use them for.
