Great Value
Cheaper than buying the MCU and Ethernet module separately. Saves space on my prototype PCB too. Highly recommended for students.

Solid Board
Good quality construction and the Ethernet speed is reliable. The only downside is the pinout labeling is a bit small to read without magnification.

Documentation Needed
Board works but examples are scarce. Had to dig through forums to find the right library for the W5500 SPI configuration.

Perfect for IoT
The W5500 module works seamlessly with the STM32. I was able to get TCP connectivity up and running within an hour. Great board for networked embedded projects.

A: No, the logic level is 3.3V. Using 5V sensors directly may damage the MCU. Please use a level shifter.
Q: Is SWD header included?
A: Yes, there is a standard 4-pin SWD header available for debugging and programming with ST-Link.
Q: What is the SPI speed?
A: The SPI interface can operate up to 80MHz, allowing for fast data transfer with the W5500 chip.
Q: Does this support Arduino IDE?
A: Yes, you can use the STM32duino package to program this board via the Arduino IDE.
