The design packages for the solenoid and analog breakouts and the digital sidecar on
this page depend on a number of external libraries that I haven't been able to find. The parts are linked to valid Digi-Key supplier information but there are no corresponding footprints. For example, the rectifier on the solenoid breakout depends on a library named FETs.IntLib, which contains the schematic, footprint, and 3D model for that part. Other parts depend on Connectors.IntLib and LEDs.IntLib. Are these FIRST-specific, and if so, where can I find them?
