Fast shipping, works immediately
Arrived well-packaged. Tested it within minutes of unboxing using the EthernetWebServer example. The link lights on the RJ45 connector respond instantly. Very happy with this purchase for my home automation gateway.

Reliable but needs 3.3V logic
Solid build quality and consistent performance. Just a reminder to beginners: this is a 3.3V device. If you are using a 5V microcontroller like an old Arduino Uno, ensure you have a level shifter. Once wired correctly, it has been rock solid in our test environment.

Great for learning networking
Bought this for a university embedded systems course. It's robust and the documentation online is plentiful. Successfully implemented a simple web server to display sensor data. No overheating issues even after running for 48 hours straight.

Superior to W5100
Upgraded from a W5100 board and the difference in performance is noticeable. The W5500 handles higher data throughput much better. Setup with the official library was plug-and-play. Excellent for industrial control prototypes.

Good value, minor pin labeling issue
The board functions exactly as described. Connection speeds are good, and it handles multiple sockets well. I deducted one star because the silkscreen labeling on the pins was slightly faint, requiring a multimeter to verify connections initially. Otherwise, great hardware.

Perfect for IoT Projects
This W5500 module worked flawlessly with my STM32 project. The SPI communication is stable, and the library support for Arduino makes integration very quick. Highly recommended for anyone needing reliable Ethernet connectivity without the overhead of a full OS.
Q: Does it support PoE (Power over Ethernet)?
A: No, this specific development board does not have built-in PoE functionality. It must be powered via its VCC and GND pins from your microcontroller or an external 3.3V power source.
Q: Is this module compatible with the Raspberry Pi Zero?
A: Yes, the W5500 module is compatible with the Raspberry Pi Zero via the SPI interface. You will need to enable SPI in the raspi-config settings and use a Python or C library that supports the W5500 chipset.
Q: What is the maximum cable length supported?
A: As long as you use standard Cat5e or Cat6 Ethernet cables, the module supports distances up to 100 meters (328 feet), adhering to standard Ethernet specifications.
Q: Does this board come with headers pre-soldered?
A: No, the module typically ships without pre-soldered headers to allow flexibility for breadboard use or direct wiring. You will need to solder your own male or female headers depending on your project requirements.
Q: Can I power this directly from the 5V pin on an Arduino?
A: While some boards have an onboard regulator, it is safest to power the W5500 chip itself with 3.3V. Check if your specific breakout board includes a voltage regulator; if not, connecting 5V directly may damage the chipset.
