Good value

Solid build quality. Setup was easy using the Arduino library. One star off because the pinout diagram was slightly faded.

Better than W5100

Upgraded from the W5100 and noticed immediate stability improvements. Handles multiple sockets well.

5 FAQ

Q: Does this work with Arduino Uno?

A: Yes, it is fully compatible with Arduino Uno using the Ethernet library.

Q: Does it support static IP?

A: Yes, you can configure both static IP and DHCP client modes in the code.

Q: Can I use this with Raspberry Pi?
