Hi all
I'm Andrea and this is my first post in this forum, I'm nice to meet all you and I hope to find out the solution about my problems that create a nightmare during my nights...

BTW, I bought on Aliexpress one card ESP8266MOD Ver0.1 Vendor AI-THINKER Lolin new NodeMCU v3 in version DEV Kit (sse the pic attached)
and used it with Arduino IDE, but I can't able to use the serial in correct mode, every time I receive spuries charatters un terminal serial console, indipendent of speed used.

The skecth is very easy, and it work fine, the LED blick as I want but no output on the serial console.

I'm using the serial via USB, the same used to load the skecth.

Please could you help me to fix this issue and understand what are wrong? Is it necessary to update the firmaware? If yes, what I must do?

Thank you to all.


Code: Select all

int i = 0;
void setup() {
  pinMode(2, OUTPUT);
  digitalWrite(2, LOW);
void loop() {

  digitalWrite(2, HIGH);
  digitalWrite(2, LOW);
