Error message wiring with an oled screen

[Melvindbt7734]

Hello
I just created a project with ESP8266, DHT22, MQ135 and Screen OLED 128x128.
I always have same error message:

The GND connector on the 128x128 OLED component must have copper top and bottom layers, but the svg specifies only one layer

PCB :

Here is my project
Platech_shematic.fzz (88.8 KB)

Anyone have any idea how I can fix this problem

Yes, your oled part is broken (it only has copper1 defined.) Replace it with the OLED-128x64-I2C-Monochrome-Display-GND-VDD.fzpz file from this post:

OLED 128x64 I2C Monochrome Display SSD1306 created

In such a case we should make a second part that matches the other common version. Do you have a url to an example of the alternate part? edit: A search of Ebay turns up an even mix of both pin layouts so I have made two new parts, one for each pin out. As you noted it is necessary to make sure you have the correct part for the module you have, because using the other one (and reversing power and ground) will likely burn out your module! Note if you want mounting holes in pcb you need to drag …

which has both layers defined correctly. You should also check to make sure your display is gnd vcc rather the vcc gnd (as both types are available and not interchangable!)
