Best bang for your buck
You get a powerful MCU and a decent screen for a fraction of the cost of other dev kits. The build quality feels premium despite the low price. Shipping was fast too.

Robust minimal system
I've used this for three different prototype projects now. The voltage regulator handles the load well, and the TFT display is bright enough for indoor testing. No issues with connectivity so far.

Great value, minor documentation gaps
Hardware quality is solid and the price is unbeatable. The only downside is that the schematic could be more detailed for advanced peripheral usage. Otherwise, it boots up instantly and programs easily via ST-Link.

Solid for prototyping control logic
We use these for initial proof-of-concept in our control systems. The processing speed is adequate for real-time tasks, and the form factor fits nicely into our test enclosures. Would buy again.

Easy setup with CubeIDE
As a beginner, I was worried about the complexity, but setting up the environment with STM32CubeIDE was straightforward. The board was recognized immediately, and the example code for the screen ran without modification.

Perfect for learning ARM architecture
This board is exactly what I needed to transition from Arduino to STM32. The included TFT screen works flawlessly with the standard libraries, and the pinout is clearly labeled. Highly recommended for students.
Q: Which software environments are compatible with this board?
A: This board is fully compatible with STM32CubeIDE, Keil MDK, IAR Embedded Workbench, and can also be programmed using PlatformIO in VS Code or via command-line tools like OpenOCD.
Q: Does this board come with a pre-installed bootloader?
A: Yes, the board comes with the standard STM32 system memory bootloader, allowing you to program it via UART if you do not have an ST-Link debugger.
Q: Is the TFT screen touch-enabled?
A: No, this specific model features a resistive or capacitive-free TFT display depending on the batch, but this version does not support touch input. It is strictly for visual output.
Q: Can I power this board directly from a 9V battery?
A: It is not recommended to connect a 9V battery directly to the 5V pin. Please use the VIN pin if your battery is regulated, or step down the voltage to 5V before connecting to ensure the onboard regulator is not damaged.
Q: Are the GPIO pins 5V tolerant?
A: Most GPIO pins on the STM32F103 series are not 5V tolerant and operate at 3.3V logic levels. Applying 5V directly to these pins may damage the microcontroller. Please use level shifters when interfacing with 5V devices.
