Greetings Everybody,

Iam new to KC and I purchased one from Aliexpress.
I connected to my PC through USB-C Type and the serial port was appeared in the Arduino IDE at com3
   
I have add all the required URL as following in the arduino
1. File
2. Preference
3. I added the link related to ESP.
4.tools-- boards--- boards manager--- esp32 installed.
5. I selected many boards such as nodemcu-32s
 
when I tried to do compile, there is error message appeared
" error compiling for board nodemuc-32s"    


I tried to change the board type from the arduino, but still same error.    

also I tried to change the programmer but still same    


everything is fine to my board
12v
c-type usb.
serial is appeared in the arduino.

I need support.
