    Nothing like high precision low jitter clocks for professional work !

    This is PWM output from Nodemcu board.


    Did not help that supply rail had a couple 100 milivolts of noise on it.

    No other I/O on it, but did see a 10 Hz 100 mV pulse on supply rail.
    Maybe thats the ALU trying to add two bytes together ... Nothing like a
    fast high speed architecture.

    Regards, Dana.
