Good value
Works well for most projects. The only minor issue is that the USB connector feels a bit loose, but functionality is not affected. Good price point.

Compact and powerful
Fits easily into small enclosures. I used this for a sensor logging project and the performance was excellent. The 256KB flash is plenty for my code.

Solid hardware
Pinout is clear and the PCB quality is decent. Make sure you have an ST-Link debugger as one is not included. Overall satisfied with the purchase.

Excellent compatibility
Used with CubeIDE and HAL libraries without any issues. Bootloaders work fine. It is a reliable minimal system board for development.

Perfect for learning ARM
Great board for students and hobbyists. The pinout is clearly labeled and it works seamlessly with STM32CubeIDE. Highly recommended for anyone starting with ARM Cortex-M3.
Q: Does this board support the Arduino IDE?
A: Yes, this board supports the Arduino IDE when you install the STM32duino board package. You can select the generic STM32F103C series.
Q: Can this board drive DC motors directly?
A: The GPIO pins cannot drive motors directly due to current limits. You should use a motor driver module controlled by the PWM outputs on this board.
Q: Is an ST-Link debugger included in the package?
A: No, the development board is sold separately. You will need to purchase an ST-Link V2 or J-Link debugger separately to program the chip.
Q: Are the GPIO pins 5V tolerant?
A: Most GPIO pins on the STM32F103RCT6 are 5V tolerant, but we recommend using 3.3V logic for optimal reliability and longevity.
Q: Which IDE do you recommend for beginners?
A: We recommend STM32CubeIDE for beginners as it is free and integrates configuration tools. Keil MDK is also an option but requires a license for larger projects.
