Great for motor control projects
Using this to control a small drone flight controller. The timers and ADCs are fast enough for real-time processing. Very happy with the stability of the board under load.

Perfect for learning embedded systems
This board is exactly what I needed to start my journey with ARM Cortex-M3. The pinout is clearly labeled, and it works flawlessly with the Arduino IDE and STM32CubeIDE. Great value for the price.

Solid performance, minor soldering needed
The chip performs well at 72MHz. Note that the header pins are not pre-soldered on some batches, so be prepared to do a little soldering work. Otherwise, a reliable development board.

Reliable for industrial prototyping
We used several of these for initial prototyping of an industrial sensor node. They have been running continuously for weeks without crashing. Highly recommended for proof-of-concept builds.

Good hardware, steep learning curve
The board itself seems genuine and well-made. However, if you are coming from Arduino, the setup for registers and clocks can be confusing. Make sure to read the datasheet carefully.

Best budget STM32 board
I bought this for my university project. It handles all my sensor inputs and PWM outputs without any issues. The community support for this specific model is huge, which makes debugging easy.
Q: Can I program this using the standard Arduino IDE?
A: Yes, you can program the STM32F103C8T6 using the Arduino IDE by installing the STM32duino board package. You will need an ST-Link V2 or a USB-to-TTL serial adapter for uploading code.
Q: Does this board come with pre-soldered header pins?
A: It depends on the specific batch. Some come with headers soldered, while others ship with loose headers requiring you to solder them yourself. Please check the product images or description variations before ordering.
Q: What is the maximum current this board can supply on the 3.3V pin?
A: The onboard regulator can typically supply around 100mA to 150mA. For projects requiring higher current, we recommend powering external components via a separate power source to avoid damaging the board.
Q: Is the bootloader pre-installed?
A: Yes, most of our boards come with the generic HID bootloader pre-installed, allowing you to program via USB if configured correctly. However, using an ST-Link debugger is recommended for the most reliable experience.
Q: Does this support MicroPython?
A: Yes, the STM32F103C8T6 has sufficient flash and RAM to run MicroPython. You will need to flash the appropriate .bin file for the Blue Pill variant using a programmer like ST-Link.
