Arduino Stackable Header - 10 Pin

Soldered it onto my Arduino Uno for senior design project. Would suggest finidng the thinnest solder you have, then using that solder thickness as a reference for finding an even thinner solder. Or whatever you want man. Just keep it clean. PRO TIP: If you are soldering onto the analog input/output pins, take the soldering iron and touch the circle contacts first a few times to make it easier for the solder to attach. Then melt a little solder onto the tip of your iron, place the header into the header contacts into the hole, and dab the metaled solder on the circle. The solder should just slide right into place. Save yourself some time and burnt fingers.

Great product for fixing those "goofs" that had to be un-soldered. Good quality, Great bargain.
