Need a source for the 2x3-pin header. Project is a shield for a DUE board and have all the 8-pin and 10-pin headers but am short the 2x3 header, any tips on who would have them? Have tried Mouser, Newark, Digi-Key and Avnet with no luck. Did find an Adafruit kit (#85) that has it but would end up throwing away five headers just to get the one 2x3. Who makes these headers?
digi-key or mouser or any of the supply houses will sell them in 40 pin sections, you just cut/break what you need.

and e-bay is another option.
