Board footprint and signal routing
The 9-146285-0-05: The unshrouded design keeps the profile low — the insulator sits 0.090" (2.29 mm) above the board — which helps when routing traces under the header body or when the mating receptacle needs clearance. For signal-level loads — GPIO, sensor inputs, low-power data — this is ample; for power distribution, derate per the temperature rise curve.
