Ideas Test


Protection against ground loops.

There's an "idiot proff way" to solve this in your next hardware revision - use isolators like Texas Instruments ISO7841 (a lot of other brands have similar products) - to isolate the USB interface from the rest of the box. This will admittedly increase the BOM, but your company will end up with an even better product. This will also allow users of more than one of your products to have more "ground planes" - one per box, so to speak.
Best wishes
