Best purchase for my engineering course
Bought this for my university embedded systems class. The compatibility with standard ST-Link debuggers is seamless, and the provided examples saved me hours of coding from scratch.

Perfect for learning STM32 G4 series
The board arrived quickly and the video tutorials made setting up the environment incredibly easy. The example code is well-commented and covers all the basic peripherals.

Excellent value for industrial prototyping
I used this for a quick proof-of-concept for an industrial sensor node. The math coprocessor on the G4 core handles the floating-point calculations effortlessly. Highly recommended.

Beginner friendly
As someone new to embedded systems, I was worried about the learning curve. The step-by-step videos broke down the IDE setup and first blink program perfectly. No issues so far.

Great hardware, minor documentation typo
The board itself is high quality and the USB-C connection is very convenient. I found a small typo in one of the PDF guides, but the video tutorial clarified everything immediately.

Solid board, wish it had more GPIO exposed
The core functionality is fantastic and stable. My only wish is that they exposed a few more GPIO pins on the headers for complex projects, but for learning, it is sufficient.
Q: Are the video tutorials accessible without an internet connection after download?
A: Yes, once you download the tutorial package from the link provided in the box, all video files and source code can be viewed and used offline.
Q: Is the USB-C port used only for power or can it transfer data?
A: On this board, the USB-C connector is configured primarily for 5V power input. Data communication for programming is handled through the separate SWD header, not the USB port.
Q: Does this board come with a built-in debugger or do I need an external ST-Link?
A: This specific model does not have a built-in debugger. You will need an external ST-Link V2 or V3 programmer to upload code and debug via the SWD header provided on the board.
Q: Can this board handle 5V logic inputs directly?
A: No, the STM32G431 operates at 3.3V logic levels. Applying 5V directly to the GPIO pins may damage the microcontroller. Please use a logic level converter if interfacing with 5V devices.
Q: Which IDE is recommended for the example code provided?
A: The examples are primarily designed for STM32CubeIDE, which is free to download. We also provide Makefiles for users who prefer command-line builds or other editors like VS Code.
