(SOLVED)Brand New NODEMCU AMICA (ESP8266MOD) not responding?

Projects Networking, Protocols, and Devices
1

The esp8266 by esp8266 community version 2.4.2 is INSTALLED.

The AMICA Module has been found by the PC at Virtual COM11 Port

There are two LEDs on the Module; none of them is ON.

A simple "hello world!" sketch is compiled, but it is not uploaded. In the middle of uploading, the following error appears and the uploading is aborted.

Is my Module bad or there any means to make it work?

You were able to upload ESP8266 Arduino Core?

You could always upload the original AT firmware.

I have followed the guidelines of the following web page to install the ESP Module:

What are you using as your 3.3V power supply ?

The ESP8266 Arduino Core firmware overrides the AT firmware.
Are you able to use AT commands to communicate with the module?
This is the simplest way to verify that the module is operational.

What are you using as your 3.3V power supply ?

Do I need to connect external 3.3V at the 3.3V-pin of the NODEMCU? Is it not like UNO, NANO, MEGA, DUE which work on USB's 5V? On the Module, I can clearly see a 5/3.3V regulator?

6

Which NodeMCU are you using? V2 or V3?

Sometimes the fuse on USB gets blown up. To give 5V to VIN might help in that case.

There is no mark for V2 or V3. This is the pictorial view of the board.

Cannot see much detail in the photo.

The ESP8266 itself is a 3.3V IC .

see if this is helpful:

1. I replaced the board with a new one; but, the same uploading problem.

2. So, this is not the problem with the board.

3. I changed (without knowing anything) the Board type into "Adafruit Feather HUZZAH ESP8266 in the Tools, and now I can upload sketch in the board.

4. As a test case, I have uploaded the following sketch which blinks the built-in LED (connected at D2) at 5-sec interval. (The "Hello!" message did not appear on Serial Monitor?)

void setup() 
{
  Serial.begin(115200);
  Serial.print("Hello!"); 
  pinMode(2, OUTPUT);
  
}

void loop() 
{
  digitalWrite(2, !digitalRead(2));
  delay(5000);

}

Thanks to all who responded to this thread.
