These stackable headers are made to work with the Particle Photon and Photon ProtoShield boards. Each header adds a great deal of connectivity to your next Photon project. Each order includes one 1x12 stackable header with pins spaced at 0.1". If you don't have a Particle Photon, that's fine! These headers will work in any other situation when you need a 12-pin header solution!
