Great value, minor pin labeling issue
The hardware quality is solid and the connection speed is reliable. I deducted one star because the silk screen pin labels are slightly faint, but once mapped out, it works perfectly.

Perfect for IoT Projects
This board works flawlessly with the Arduino IDE. The W5500 chip handles network connections much better than older ENC28J60 modules. Setup was straightforward using the Ethernet library.

Excellent STM32 Integration
Using this with the native STM32duino core provides excellent performance. The SPI communication is fast and the TCP/IP stack offloading by the W5500 saves significant MCU resources.

Stable Ethernet Connection
I used this for a home automation sensor node. It has been running continuously for three weeks without dropping the connection. Highly recommended for stable networking needs.
Q: Is this board compatible with the standard Arduino Ethernet library?
A: Yes, it is fully compatible with the standard Ethernet library when using the appropriate pin definitions for the CS pin, typically defined in your code setup.
Q: Does this module support PoE (Power over Ethernet)?
A: No, this development board does not have built-in PoE capability. It must be powered via the VIN or 5V/GND pins using an external power source.
Q: Are there example codes available for MQTT protocol?
A: While the board itself handles the physical and link layers, many community libraries exist for MQTT on top of the Ethernet library. We recommend checking GitHub for 'W5500 MQTT' examples.
Q: What is the maximum cable length supported for stable connection?
A: It supports standard Ethernet cable lengths up to 100 meters (328 feet) when using Cat5e or Cat6 cables, adhering to IEEE 802.3 standards.
Q: Can I use this with a 3.3V logic level microcontroller?
A: Yes, the W5500 chip operates at 3.3V, and the board includes necessary circuitry to be safe for 3.3V logic systems, though always verify your specific MCU voltage requirements.
