Solid performance
Works exactly as described. The build quality feels sturdy. I deducted one star only because the onboard LED is a bit dim, but that's a very minor complaint for the price point.

Great value, minor documentation gaps
The hardware quality is excellent and the clock speed is stable at 72MHz. However, finding specific datasheets for the GD32 series took a bit more digging than usual compared to STM32 resources. Still, highly recommended for experienced users.

Perfect drop-in replacement
I needed a cost-effective alternative to the STM32 for a bulk project, and this board works flawlessly. The Type-C connector is a nice modern touch, making it easy to connect without worrying about cable orientation.

Excellent for prototyping
We ordered ten of these for our lab. All units passed initial testing. The compatibility with existing STM32 libraries saved us a lot of development time. Will definitely order more.

Reliable and fast shipping
Used this board for a home automation sensor node. Power consumption is low, and the Type-C port handles power delivery smoothly. No issues after two weeks of continuous operation.

Ideal for learning ARM architecture
Bought this for my university embedded systems course. It compiles code easily using standard IDEs. The pin layout is identical to the blue pill boards I'm used to, so no redesign was necessary.
Q: Can I use ST-Link V2 to program this board?
A: Absolutely. The board features a standard SWD header, making it fully compatible with ST-Link V2 and other standard ARM debuggers/programmers.
Q: Are there any differences in instruction set compared to STM32F103?
A: The GD32F103 uses the same ARM Cortex-M3 core, so the instruction set is identical. However, some peripheral register addresses or clock configurations might differ slightly, so please refer to the GD32 reference manual for advanced peripheral usage.
Q: What is the maximum input voltage for the VIN pin?
A: While the board operates at 3.3V, the onboard regulator typically accepts an input voltage between 3.3V and 5V via the VIN pin or USB. We recommend staying within 5V to ensure stability.
Q: Is this board compatible with the Arduino IDE?
A: Yes, this board is compatible with the Arduino IDE. You will need to install the appropriate GD32 board support package or use the generic STM32 core, ensuring you select the correct pin mapping.
Q: Does it come with a USB cable included?
A: Yes, the package includes a high-quality USB Type-C to Type-A cable for programming and power supply.
