Solid hardware, needs careful pinout check
The board functions well for prototyping. Just make sure to double-check the pinout diagram as it differs slightly from standard Arduino layouts.

Tiny but powerful
Impressed by how much processing power is packed into such a small form factor. Used it to control a small drone flight controller successfully.

Perfect for learning ARM Cortex-M3
This board is incredibly compact and works flawlessly with the STM32CubeIDE. Great value for money for anyone wanting to move beyond Arduino.

Good starter board
Works great out of the box. The only downside is the lack of an onboard programmer, so you need a separate ST-Link debugger.

Reliable and consistent
I have purchased five of these for various sensor nodes. All of them performed consistently without any issues. Highly recommended.

Best budget MCU board
Bought this for my university embedded systems project. It handles complex tasks easily and the community support online is huge.
Q: Is this board compatible with the Arduino IDE?
A: Yes, it is compatible. You can program it using the Arduino IDE by installing the appropriate STM32 board support package via the Board Manager.
Q: Does this specific model have a built-in LED on pin PC13?
A: Yes, most versions of the STM32F103C8T6 minimum system board include an LED connected to pin PC13, which is commonly used for blinking tests.
Q: What is the maximum current this board can supply on the 3.3V pin?
A: The onboard regulator can typically supply up to 200mA, but we recommend keeping the load under 100mA for stable operation and to prevent overheating.
Q: Can I power this board directly via the VIN pin with 5V?
A: Yes, you can apply 5V to the 5V pin (often labeled as VIN on clones), which passes through the onboard regulator to provide 3.3V to the MCU.
Q: Does this board come with a USB cable or programmer?
A: No, this package includes only the bare minimum system board. You will need to purchase a separate ST-Link V2 programmer/debugger and a micro-USB cable.
