Best budget development board
I bought three of these for my university project. They are incredibly cheap compared to official Nucleo boards but offer similar performance for basic tasks. Uploading code via ST-Link was seamless.

Good board, documentation could be better
Hardware is top-notch for the price. The only downside is that you need to know how to configure the clock settings manually if you aren't using the Arduino core. Once set up, it flies.

Exceeded expectations
Fast shipping and the board arrived in perfect condition. I'm using it to control a small drone flight controller, and the processing speed is more than adequate. Highly recommended for DIY robotics.

Perfect for learning ARM Cortex-M3
This board is exactly what I needed to start my embedded systems journey. It works flawlessly with the Arduino IDE and STM32CubeIDE. The pinout is clearly marked, and the build quality feels solid for the price.

Reliable for prototyping
We use these in our makerspace for workshops. They are robust enough to handle beginner mistakes and powerful enough for intermediate projects involving PWM, ADC, and UART communication.

Great value, minor soldering needed
The chip is genuine and runs at the specified 72MHz without issues. Note that the header pins are not pre-soldered on some batches, so be prepared to solder them yourself. Otherwise, a fantastic minimum system board.
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 without them to reduce shipping volume. Please check the product images or description at the time of purchase.
Q: Is this compatible with the Arduino IDE?
A: Yes, it is fully compatible. You need to install the STM32 board package by STMicroelectronics or the Maple Core in the Arduino Board Manager to get started.
Q: Does it support floating point arithmetic?
A: The STM32F103C8T6 uses a Cortex-M3 core which does not have a hardware Floating Point Unit (FPU). Floating point operations are handled in software, which is slower than on M4 or M7 cores.
Q: What is the maximum current this board can supply to peripherals?
A: The onboard LDO regulator can typically supply up to 200mA total for the board and connected peripherals. For high-current devices like motors, please use an external power source.
Q: Can I power this board directly via USB?
A: No, this minimum system board does not have an onboard USB-to-UART converter. You will need an external ST-Link V2 programmer or a separate USB-TTL adapter to power and program it.
