- Ethernet Shield W5100
KEY FEATURES OF ETHERNET SHIELD W5100:
- WIZnet W5100 Ethernet controller
- Compatible with both Uno and Mega footprints
- Standard RJ-45 CAT network connector
- Auto MDI/MDIX (auto cable pin swap)
- Acts as client or server
- TCP/IP protocols include TCP, UDP, ICMP, IPv4 ARP, IGMP, Ethernet
- 10BaseT/100BaseTX Ethernet PHY embedded
- Up to 4 simultaneous socket connections
- MicroSD card slot
- SPI Interface
- 5V compatible, operates at 3.3V internally
- Good library support
This Ethernet shield uses the WIZnet W5100 network interface chip to provide a cabled connection to a network. The board also has an SD Micro card slot for data storage. The board does not support wireless Ethernet.
The W5100 is an older chip, but has very good library support and tends to be the go-to for wired Ethernet for Arduino and compatibles. The shield is compatible with both the Uno and Mega style footprints and uses the SPI interface which is picked up from the ICSP header.
