When using an intel edison with the Arduino breakout board I noticed that using the led.blink() on any of the PWM pins would not turn the led off completely. I placed a scope on the PWM output and noticed that when the led is dim that there is actually a PWM signal with a pulse width of 2.7 micro seconds and a period of 702 microseconds. This occurs on any of the PWM pins with the Intel Edison using the Arduino Breakout board.
