Single row of 30-holes, female header with swiss round machined pins. These units have very high quality round pins to accept and retain machine pin headers much better. Can be cut to size with a pair of wire-cutters. Standard .1" spacing. We use them extensively in the Olimex development boards. They mate very well with break away headers.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

These pins are great to work with. They don't take chips (8 pin-28 pin) as easily as normal female headers, you have to work the pins on the chip to align them with the headers holes before you put them into these. Where they really shine is how they hold the chips. They lock into place securely and once in, the chip won't move, no intermittents, no loose connection, and once the chips pins are shaped, they slide right in and out easily. They're easier to snap apart than typical female headers for defined length and they have a lower profile. I much prefer these to normal female headers.
