Great value, minor soldering needed
The board functions well and the chip is genuine. Note that some header pins might need to be soldered on depending on your specific kit version. Once set up, debugging via SWD is smooth.

Reliable for university projects
Used this for my embedded systems final project. It handled all our sensor inputs and PWM outputs without any issues. The documentation provided by the seller was also very helpful.

Good standard version
Does exactly what it says on the tin. No fancy extras, just a solid development board. The USB connector feels a bit fragile, so be careful when plugging and unplugging frequently.

Excellent for motor control
I am using this to control a small DC motor driver. The timer peripherals are easy to configure, and the processing speed is more than adequate for real-time control loops.

Compact and powerful
Impressed by how much functionality is packed into such a small board. The 256KB flash is plenty for most intermediate projects. Bootloader entry is easy using the jumpers.

Perfect for STM32 learning
This board is exactly what I needed to start learning ARM Cortex-M3 programming. The pinout is clearly labeled, and it works flawlessly with STM32CubeIDE. Highly recommended for beginners.
Q: Can I power this board directly via the 5V pin?
A: Yes, you can supply 5V to the 5V pin, but ensure the voltage is regulated and stable. Alternatively, powering via the micro-USB port is the safest and most common method for development.
Q: Does it come with headers pre-soldered?
A: The standard version typically comes with pin holes ready for soldering, but headers are not always pre-soldered to keep shipping costs low. Please check the specific product images or description for 'pre-soldered' variants.
Q: Is this board compatible with the Arduino IDE?
A: Yes, you can use this board with Arduino IDE by installing the appropriate STM32 core package (e.g., STM32duino). You will need to select the correct board definition for the F103RC series.
Q: What is the maximum current draw per GPIO pin?
A: According to the STM32F103RC datasheet, each I/O port can sink or source up to 25mA. However, the total current sunk or sourced by all ports combined should not exceed the limits specified in the official datasheet to avoid damage.
Q: What debugger do you recommend for this board?
A: This board supports both JTAG and SWD interfaces. We recommend using an ST-Link V2 or V3 debugger as it is cost-effective and widely supported by major IDEs like Keil, IAR, and STM32CubeIDE.
