XBees are so cute and tiny but if you're using them in a circuit you'll be annoyed to find that your classic 0.1" headers don't fit them! That's because they use 2mm spacing instead of 2.54mm spacing. That's why you need special sockets like these ones! As of Tuesday, June 16th, 2015 we are selling two sockets together instead of just one! These sockets have 10 pins, spaced 2mm apart. Check the...

These two Female Stacking Headers alone are, well, lonely. But pair them with any of our Feather boards and you're in business! What do they do? They stack. Put the headers through your Feather and then you can not only plug them into a solderless breadboard, but you could attach circuitry on top as well Note : Comes with one 12-pin and one 16-pin header, Feathers not included

These two  Female Headers  alone are, well, lonely. But pair them with any of our Feather boards and you're in business! What do they do? They get soldered on either side of the Feather board.
