Common Pin Assignments
Pin assignment is only needed for ESP chips that have an USB-OTG peripheral. If your board doesn't have a USB connector connected to the USB-OTG dedicated GPIOs, you may have to DIY a cable and connect D+ and D- to the pins listed below.
ESP BOARD USB CONNECTOR (type A)
--
| || VCC
[USBPHY_DM_NUM] ------> | || D-
[USBPHY_DP_NUM] ------> | || D+
| || GND
--
Refer to soc/usb_pins.h
to find the real GPIO number of USBPHY_DP_NUM and USBPHY_DM_NUM.
USB_DP | USB_DM | |
