Perfect for STM32 learning
This core board is exactly what I needed to start my embedded systems journey. All pins are clearly labeled and broken out, making it easy to connect to breadboards. The 72MHz speed is more than enough for my robotics projects.

Good starter board
If you are moving from Arduino to ARM, this is a great step up. The learning curve is slightly steeper, but having all IOs accessible makes debugging much easier. Lost one star because the silk screen could be clearer.

Compact and powerful
Small form factor fits perfectly into my custom enclosures. The power regulation is stable, and I haven't experienced any resets during long-running tests. Highly recommended for IoT prototypes.

Exceeded expectations
Bought three of these for a drone controller project. They are lightweight, fast, and the community support for STM32F103 is massive. No issues with flashing firmware via ST-Link.

Great value, minor soldering needed
The board works flawlessly with the Arduino IDE and Keil. Note that you may need to solder headers yourself depending on the specific variant shipped, but the quality of the PCB is excellent for the price.

Reliable for university projects
Used this for my final year control systems project. It handled ADC readings and PWM generation without any hiccups. The documentation provided by the seller was also very helpful.
Q: Is this compatible with the Arduino IDE?
A: Yes, this board is fully compatible with the Arduino IDE. You will need to install the STM32 board package via the Board Manager and select the appropriate generic STM32F103C8T6 board profile.
Q: Does this board come with pre-soldered pin headers?
A: It depends on the specific option selected at checkout. Most standard versions ship without headers to allow for flexible mounting, but you can easily solder them on yourself.
Q: Can I power this directly from a 5V USB source?
A: Yes, the board features an onboard voltage regulator that accepts input voltages typically between 3.6V and 6V, so connecting it to a 5V USB source is safe and standard practice.
Q: What debugger do I need to program this board?
A: You can use any standard ST-Link V2 or V3 programmer/debugger. It connects via the SWD interface pins located on the edge of the board.
Q: How much current can the GPIO pins source?
A: Each GPIO pin can typically source or sink up to 25mA. However, the total current for all ports combined should not exceed the limits specified in the official STM32F103C8T6 datasheet to ensure stability.
