## Components

- **WIZnet W5200** x 1 ([docs](https://docs.wiznet.io/Product/iEthernet/W5200/))
- **WIZnet W5500** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5500))

WIZnet parts: W5500 ([Datasheet](https://docs.wiznet.io/Product/Chip/Ethernet/W5500/datasheet?utm_source=maker&utm_medium=project&utm_campaign=w5500), [product hub](https://maker.wiznet.io/products/w5500/))

## Article

This content is an article explaining how to use Ethernet in Arduino.
The author expresses that to use Ethernet in Arduino, use W5100/W5200/W5500 and ENC28J26.

Also, the memory of Ethernet.h and UIPEthernet.h is compared, and if the memory is insufficient, it is recommended to use W5100/W5200/W5500.
And he directly connected the ENC28J26, W5200, and W5500 to Arduino and conducted the test.
