## Components

- **ESP8266** x 1: ESP8266
- Software: **WIZnet LWIP W5500**

## Article

Example of using SPI Ethernet module with esp8266. Arduino core for ESP8266 uses [lwip](https://savannah.nongnu.org/projects/lwip/) for TCP/IP protocol stack. The hierarchy of programs that use WiFi is as follows:

```
+----------------+
|  Application   |
+----------------+
| Network Object |
+----------------+
|      lwip      |
+----------------+
|   WiFi Driver  |
+----------------+
```

Arduino Core for ESP8266 Ver3.0.2 officially supports SPI External Ethernet. **You don't need any libraries.** The hierarchy of programs that use Ethernet is as follows:

```
+----------------+
|  Application   |
+----------------+
| Network Object |
+----------------+
|      lwip      |
+----------------+
| Ethernet Driver|
+----------------+
```
