W5500 performance is solid
The TCP/IP stack offloading to the W5500 works great. I achieved consistent throughput for my sensor data uploads. Only minor issue was the silk screen labeling being slightly faint on my unit.

Robust for Industrial Control
I've deployed five of these in a factory setting for data logging. They handle the noisy environment well, and the RS485 communication is stable over long distances. Highly recommended for control systems.

Great value but docs could be better
Hardware quality is solid for the price. I managed to get the Ethernet port running with STM32CubeIDE quickly. However, finding specific pinout diagrams for the CAN interface took some digging in the community forums.

Excellent learning board
As someone transitioning from Arduino to ARM, this board was a gentle introduction. The inclusion of multiple communication protocols on one board saves so much space on my breadboard setup.

Perfect for IoT Prototyping
This board is exactly what I needed for my industrial monitoring project. The W5500 chip makes setting up Ethernet connectivity incredibly easy without needing a complex OS. The RS485 and CAN ports work flawlessly out of the box.

Best bang for your buck
You rarely find a board with Ethernet, CAN, and RS485 at this price point. The build quality feels premium, and the soldering joints are clean. It's now my go-to recommendation for students.
Q: Does this board support Power over Ethernet (PoE)?
A: No, this specific model does not have built-in PoE capability. You will need to supply power via the VIN pin or USB connector separately.
Q: Which IDEs are compatible with this STM32F103C8T6 board?
A: It is fully compatible with STM32CubeIDE, Keil MDK, IAR Embedded Workbench, and can also be programmed using PlatformIO with VS Code.
Q: What is the maximum baud rate supported on the RS485 interface?
A: The RS485 interface supports standard baud rates up to 115200 bps reliably, though higher speeds may be achievable depending on your specific wiring and environment.
Q: Is the CAN transceiver integrated or do I need an external module?
A: The board includes an integrated CAN transceiver, so you can connect directly to a CAN bus using the provided terminal blocks or pins without extra hardware.
Q: Can I use this board with 5V logic sensors?
A: Yes, the GPIO pins are 5V tolerant, allowing you to interface directly with 5V logic sensors without needing a level shifter, but please verify specific pin constraints in the datasheet.
