    The ‘ESP32 S3 DevKitC1 Clone’ board has a jumper called ‘RGB’ and another called ‘USB-OTG’, both are open. But it may be necessary to solder the jumper for the devices to work.

  2. R says:

    The ‘ESP32 S3 DevKitC1 Clone’ board has a jumper called ‘IN-OUT’.

    “In-Out, when closed, bypasses one diode, making USB VBus power coming to 5Vin. If 5Vin is also connected to external source, it can get back-fed by USB, which is usually undesirable. But USB bus is protected by another diode, it cannot get back-fed by external source.

    When In-Out is open, 5Vin and USB VBus are separated by diode, USB power does not come to 5Vin.

    USB-OTG jumper, when closed, connects together USB VBus lines from both USB-C connectors.”

  3. R says:

    The RGB led did not work with common digitalWrite() commands. LED only worked with neopixelWrite() commands.

    “There is a BlinkRGB under the ESP32->GPIO examples that uses the onboard RGB LED.”
