Solved my multi-protocol headache
I needed a solution that could talk to legacy Modbus devices via RS485 and send data to the cloud via Ethernet. This board does exactly that out of the box. The 1G flash allows for substantial buffering.

Great hardware, documentation could be better
Hardware quality is excellent and the pinout is logical. However, finding specific example code for the W5500 driver took some digging. Once set up, the Ethernet performance is very stable.

Good learning tool for STM32
As a student, this board offers great value. Having multiple communication protocols on one board helps me understand how to manage resources on the Cortex-M4. The flash memory speed is impressive.

Robust build quality
Used this in a factory environment for two weeks now. The terminal blocks are sturdy, and the board handles electrical noise on the RS485 lines very well. Highly recommended for prototyping.

Powerful but steep learning curve
The board is very capable, but if you are new to STM32 development, be prepared to spend time setting up the toolchain. It's not a plug-and-play Arduino experience, but the performance is worth it.

Perfect for industrial networking projects
The integration of the W5500 chip with four independent RS485 channels makes this board a powerhouse for gateway applications. The 1GB flash is a huge bonus for local data logging without needing an SD card.
Q: What is the maximum baud rate supported on the RS485 channels?
A: The UART peripherals driving the RS485 transceivers support baud rates up to several Mbps, typically limited by the cable length and network conditions rather than the board itself.
Q: Can I use the Keil MDK or STM32CubeIDE for development?
A: Yes, the board is fully compatible with both Keil MDK and STM32CubeIDE. Standard ST-Link or J-Link debuggers can be used via the SWD interface.
Q: Does this board support PoE (Power over Ethernet)?
A: No, this specific model does not have built-in PoE functionality. It requires a separate 5V DC power supply via the terminal block or header.
Q: Are schematic diagrams available for this board?
A: Yes, detailed schematic diagrams and PCB layout files are available for download in the 'Documents' section of the product page to assist with custom carrier design.
Q: Is the 1GB flash memory accessible as a standard file system?
A: Yes, when configured with the appropriate firmware (like FatFS), the flash memory can be mounted as a file system for storing logs, configuration files, or firmware updates.
