    "data": {
        "note": "The refresh frequency sets the frame: a standard 50 Hz servo signal has a 20 ms (20,000 µs) period, so a 1500 µs pulse is just 7.5 % duty cycle. The servo only cares about the pulse width, but the controller's PWM peripheral is configured in duty, so this conversion sets the timer. Digital servos and multirotor ESCs often run faster frames (e.g. 333 Hz) for crisper response — drop the frequency in to see the new duty.",
