The Carrier comes with a combo 3-in-1 SMD/TH/FlexyPin Stamp footprint, you can solder the Stamp directly to the Carrier, use 2mm pin headers + sockets to be able to plug it in and out, or use FlexyPins to pop the Stamp in and out of the Carrier would soldering the Stamp. This way the Carrier also acts as a great Stamp flashing and testing jig.
