@jcabad100 For me the noise happens when
- The FIRE is turned on and I press the power button (the one next to the USB port)
- The FIRE is being programmed by the Arduino SDK and switches into the download mode. It lasts maybe 2, 3 seconds in total and always disappears
The reason for this, I guess, is that the speaker pin (GPIO25) is sitting right next to the RST pin, and most likely the lines are interfering.
As for the magnetic dock not providing USB connection... There are two data pins exposed, so I suppose USB communication should be possible up until the GO bottom module. However they're connected to GPIO21 and 22 as I2C pins.
