For some one who is beginner, and he only knows little about Arduino uno and knows that esp32 is a similar but relatively advanced system, how we can explain difference between esp32 and node mcu because I have seen some someone who plugged an esp32 into USB port of their laptop but Arduino ide was showing node mcu on com port
Is Arduino ide considering esp32 and node mcu exactly same thing?
NodeMCU usually refers to a development board based on the ESP8266 module, while ESP32 is the microcontroller module itself, which is more advanced and comes with additional features like Bluetooth support.
This might be because the USB Vendor ID and Product ID are possibly the same for both boards.
When you launch the ide it shows the previous settings. I have an ESP32 devkit connected to my USB but this is what I see
when I select the correct port
Then you need to select the correct board - in my case ESP32 Dev module.
As a beginner you will need to look at the specs to see which best fits your needs
If you examine the devices connected to your USB with UsbTreeView (Indispensible for resolving connection issues)
you will see that it identifies the unit connected to that USB port - which is just the USB/TTL bridge, eg
Silicon Labs CP210x USB to UART Bridge
so beyond that the computer doesnt know what its connected to.
