The Analog Discovery signal cable assembly, or flywire, is the same assembly that ships with every Analog Discovery and Analog Discovery 2 we sell. We've heard from our users that it would be nice to be able to leave their Analog Discovery's wired into one project while still being able to use it on another, and so now we sell the fly wire separately! This assembly features a 2x15 keyed female pin connector, with each of the the 30 signals broken out into separate color-coded female connectors.
