different connection between USB shield and GND
Added by laforge about 3 years ago.

Description
related to the way how GND is connected to the USB shields of J2 and J3:
Currently, there is only a capacitor (C44 and C48). We would like to
- add a 1M resistor 0603 in parallel to the capacitor
- increase the footprint from 0402 to 0603 for C44 and C48
related to the way how GND is connected to the USB shield of J1:
- currently there's a direct connection. let's use the same approach as for J2 and J3, i.e.
- capacitor and resistor in parallel between shield and GND

Implemented for J2 and J3
Also for J1. Note that the shield filter components were only connected to one of the shield connector pins in the original design, so I did not modify this. If you'd prefer there to be a trace linking them on the board, please let me know.
- Status changed from New to In Progress

No, I'm fine with this, as the USB receptacle's shield shall connect both THT solder pads anyways. As long as 'the other' pad is isolated from GND, it's ok.
