Background noise #11

Hi, I have a backgound digital noise issue. This probably come from the DSP/uC circuit (clock?) on HH kit.

  1. Normal on this version?
  2. I want too try to solve this but I need circuit and DSP/uC pinout or the help from the conceptor.

I've working a day to solve this issue. I think is a ground leakage or looping from the "teansy" board. I saw a lot of complain about this circuit on the net. It's very important too isolate the analog and digital ground, isolate the ground plane too and youse a net star for grounding.

The led PWM are also noisy but in low frequency.
