Ref.: YD-ESP32-S3 N16R8
-
The device uses the ESP32-S3 chip, which can be used for the test prototype of the Internet of Things application and can also be used for practical applications. It is equipped with two USBs, one is a hardware USB-to-serial port (CH343P WCH Qinheng), and the other is ESP32-S3 usb port.

Pinout:
-
The ‘ESP32 S3 DevKitC1 Clone’ board has a jumper called 'RGB', another called 'IN-OUT', and another called 'USB-OTG', all open. But it may be necessary to solder the jumper for the devices to work.
-
- The 'IN-OUT' jumper, 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.
-
- The 'USB-OTG' jumper, when closed, connects together USB VBus lines from both USB-C connectors.
-
The RGB LED did not work with common digitalWrite() commands. RGB LED only worked with neopixelWrite() commands.
-
- Arduino IDE: There is a BlinkRGB under the ESP32->GPIO examples that uses the onboard RGB LED.
-
- Need add: '#define RGB_BUILTIN 48'
-
- Avoid looking directly at the LED, place a sheet of paper or a piece of white plastic material over the LED to serve as a diffuser.
