I have just collected the following fresh ESP32 S2 Mini Dev Board (Fig-1) equipped with USB C Type Connector. I followed a simple online tutorial to blink onboard LED with no succcess. My board is not seen by the PC. (Is it broken?)
Figure-1:
Questions: to the respected Forum Members:
1. Is it seen by PC as COM device or USB devcie?
2. If it is a COM device, then where is the USB/UART Converter chip?
3. If it is a USB device, then why is the tutorial not telling to install driver?
The ESP32-S2 Series has a native USB OTG interface: https://www.espressif.com/en/products/socs
Please check if the cable that you're using is good.
That cable works well with USB C Connector of UNOR4WiFi.
One online Tutorial has said that some of the ESP32 S2 Boards conatain integrated USB/UART Interface for cost effective solution. In such case, my board should be seen as a COM device by the PC -- but NOT!
have you installed the ESP32 libraries/drivers etc in the Arduino IDE?
if you open the Windows device manager and plugin/unplug the ESP32-S2 does anything appear/disappear possibly indicating a missing driver?
my ESP32-S3-DevKitC-1 is found OK and a COM port created
Yes!
I have installed (lnog ago) Board Files for ESP32 that supports ESP32 S2.
anything on the device manager?
did you try pressing the 0 and RST switch? see get_started_with_arduino_s2
there a number of videos on youtube - maybe be worth looking at them, e.g. https://www.youtube.com/watch?v=Ull2gCKb1Yw

Your link has provided an excellent schematic. I am looking for a step-by-step Tutorial using Arduino IDE and C++ and NOT Python.
Finally, the ESP32 S2 Mini Dev Board is made functional by blinking the onboard LED (at GPIO15). The steps that I have followed:
1. I have connected the Board with PC.
2. I have checked the 3.3V output of the 5V/3.3V regulator
3. I have pressed and hold the SW-0 switch. (post #7 @horace)
4. I have pressed and released the SW-RST switch. (post #7 @horace)
5. I have heard a dong sound and have checked the Device Manager.
6. It is seen that the PC (Windows 10) has detected the Board at COM6 Port.
7. I have opened the IDE (1.8.19) and have selected "LOLIN S2 Mini" board (ESP32 Arduino ------> LOLIN S2 Mini.
8. I have cross checked the COM6 Port selection.
9. I have opened the Blink sketch from the IDE Examples.
10. I have compiled and uploaded the sketch.
11. The onboard LED is blinking at 1-sec interval.
12. I am happy and shraing my hapiness with all the Forum Memebers and particulalrly those who have participated in this thread and guided me.
Thank you for mentioing this tip which has made the board acquiring a COM Port.
