#84960 I have a board that says “HW-628 V1.1” its usually sold as NodeMCU v3, it has 4mb.

I followed this tutorial with the Arduino IDE: https://randomnerdtutorials.com/esp8266-web-server/

But as soon as it resets the “on” led is only working for like 0.1 seconds, and then I guess it crashes.
Then I uploaded just an empty void setup() {} and void loop(){} and does the same.
I’ve just received the board an hour ago, I was very excited but I don’t know what I’m doing.

My guess is that I’m not selecting the correct board in the Arduino IDE, I tried Generic 8266 Module and NodeMCU 1.0, I’m able to flash but it does not work. Get board Info says: Unknown board.
