Teensy 4.1 USB HOST GND & Shield

[jdev]

For a new PCB design, I'm adding an onboard USB-A connector for the Teensy 4.1.

From the bottom of the Teensy 4.1, the pinouts are GND, GND, D+, D-, 5v. Hence, looks like there are two GND pins.

Should one of the GND pins be connected to Shield?

Indeed two GND - AFAIK just to accommodate typical 5 pin connector - with two GND's as was done on the T_3.6. Both are the same GND - so yes GND to shield so everything has a common reference

Great, thank you @defragster
