Hi !
I'm new to the "microcontroller world" so don't hesitate to ask detail or correct me if needed :D

I own this kit https://www.amazon.fr/gp/product/B07T2H5QXC/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

I'm trying to make the display work (simple Hello world from the doc)

I attached the way i wired everything and a small video of what is displayed, because i cannot describe the issue using word.

This is the code running

const SCL = D5;
const SDA = D4;

function start(){
 g.clear();
 g.drawString("Hello World!",2,2);
 g.flip();

  setTimeout(start);
}

// I2C
I2C1.setup({ scl:SCL, sda:SDA });
var g = require("SSD1306").connect(I2C1, start, {
  contrast: 1
});

I hope someone will be able to help me getting started

Thanks in advance !

Nevermind...
After reading carefully the amazon page, i discovered that i was using the wrong driver.
