Wiring Safety Check

Check the electrical contract before code or power is applied. A board's input voltage or per-pin maximum does not prove that a connected signal or total rail is safe.

Intake

Record the exact board/module and logic voltage, sensor/actuator part number, each rail, signal direction, VIH/VIL/input maximum, current and startup peak, pull-up location/value, ground path, cable length, protection, default state, and whether a level shifter, driver, flyback path, fuse, or current limiter is present.
