USB port section for ESP32-S2 saola dev board
Posted: Sat Jan 22, 2022 11:14 pm
I am referring to ESP32-S2 Saola-1 schematic:

My board isn't the latest so it has a single microUSB. The USB port section looks like this:
I see there are 4 resistors in the right side box. The two on top and bottom are connecting D- and D+ to CP2102, correct? If I remove them I can access the S2 USB-OTG via onboard microUSB connector because the middle two 0-ohm resistors connect the S2 USB OTG D- and D+ to the microUSB connector, also with 22pF caps (probably S2 USB OTG needs this value). Correct?
