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.
