This 1.27mm pitch, 2x5 male SMT Box Header is the same one used on our SWD Cable Breakout Board. The header alone is great if you want to incorporate this piece of hardware with your own software. We're specifically selling it so you can solder it onto our nRF52 Feather to add SWD debug/connect capabilities. You could also straighten out the SMT pins to solder into a thru-hole connector.
