WPy, GPy Noise



  • I am seeing noise that is present on signal and power pins of the module. It is not something coming from my 5V supply. As you can see by the pic below it is @~10Hz (look at the 20ms division, not freq calc as that is not accurate).

    The noise is not present when the module is in reset. Only after boot does it start. I removed all user code and have a fresh firmware installed.

    What is the source of this?
