Stacking Header Set for Beagle Bone Capes (2x23)Stack to the max with our Beagle Bone Proto Cape using these ingenious stacking headers. They're similar to 2x23 0. 1" spaced female headers but with extra long 'legs' so you can solder it through a PCB and plug it into the Bone. You can stack as many as you'd like for modular design. Each package comes with two pieces of 2x23 header, so you only need one set per Proto Cape kit. Note: The Proto Cape is not included and must be purchased separately.
