Good board, missing schematic
The hardware works perfectly but I wish there was a downloadable schematic included in the package for custom modifications.

Great for beginners
Easy to set up with Keil MDK. The pinout is clearly labeled which helped me a lot during my first embedded project.

Excellent build quality
Pins are labeled clearly and the PCB feels sturdy. I have used it for several weeks without any issues.

Perfect for IoT projects
Low power consumption verified. I am using this for a sensor node and the battery life is impressive.

Fast shipping
Works perfectly out of the box. Arrived earlier than expected and was well packaged.
Q: Can I power it with 9V?
A: No, the maximum recommended input voltage is 5V. Applying 9V directly may damage the voltage regulator.
Q: Are pin headers soldered?
A: Yes, all standard pin headers come pre-soldered for immediate use.
Q: Does this support Arduino IDE?
A: Yes, this board is compatible with the Arduino IDE via the STM32duino package.
Q: Is the chip pre-flashed?
A: It comes with a basic bootloader test firmware to verify hardware functionality before use.
Q: Is the debugger included?
A: No, the board does not include an on-board debugger. You will need a separate ST-Link programmer.
