There are a large variety of components and their footprints standardized by IPC-7351. Working to this standard promotos reliability and quality among fabrication and assembly houses. As such, the Association Connecting Electronics Industries (IPC) developed IPC-7351, the Generic Requirements for Surface Mount Design and Land Pattern Standards. The industry specifies standardized packages along with standardized footprints to support package conformity among vendors. Component packages incorporate anywhere from two conductive leads to hundreds of leads. Diverse arrays of electrical component packages and their associated footprints exist on the market today. Footprints describe the conductive interfaces where electrical components mate with the PCB. I think if you tried to replace it you’d find your replacement very similar to the original sidecar, or not very effective.Part of circuit board design is creation of component footprints. Honestly, it’s more than just a breakout board, it handles a lot of the stickier electrical and signal conditioning aspects for you as well, as well as physical compatibility. I can’t even imagine the havoc of having to inspect so many different versions of the standard unit and making sure they’re compatible. It simply isn’t feasible, especially since it falls in the realm of “allow one, allow all”. While your system may not affect that performance at all, it’s additional burden on the inspectors and other crew members to ensure your custom approach is as valid as the standard approach every other team uses. Since the refs and inspectors and FTAs rely on the expected behavior of the robot signal light, I suspect they’ll be rather stubborn on this particular requirement. is satisfied because the breakout board is a digital sidecar in all important respects (electrically equivalent).
As I see it, the breakout is merely a modification of the sidecar and breakouts, as if I had disassembled two sidecars and glued their respective PCBs together, which would not violate.
