ESP32-C3-MINI-1-H4 D+/D-

Hello! I'm wondering why on the peripheral diagram for the C3 MINI the D+ and D- pins show 0R resistors.
Is this because they can be configured as GPIO pins?
If I want to use these pins for USB do I need to add resistors and if so, what value?
Thanks!

I think they're there in case you have issues with EMC leaking out through your USB lead or something: you can replace them with something that filters that in that case. If you don't think that's an issue, you can leave them off (=replace them with a short)
