    "data": {
        "note": "A hobby RC servo reads the width of the pulse, not a PWM duty cycle: the standard 1000–2000 µs maps linearly across the travel, with 1500 µs at centre. angle = (pulse − min) ÷ (min-to-max span) × the travel. Many servos accept a wider 500–2500 µs for extra throw, but pushing past the mechanical stops strains the gears — the unclamped value here shows when a pulse asks for more than the configured range.",
