Reliable but documentation could be better
The hardware quality is good and consistent across the batch we ordered for our makerspace. However, beginners might struggle slightly as the included manual is very basic. You'll need to rely on online community resources.

Fast shipping and genuine chip
Arrived quickly and well-packaged. I verified the chip ID using OpenOCD, and it is indeed a genuine STM32F103C8T6. No issues with flashing firmware or debugging. Will buy again.

Solid core board, minor soldering needed
The chip itself is genuine and runs at the expected 72MHz. Note that this is a bare minimum system board, so you will need to solder headers if you want to plug it into a breadboard easily. Otherwise, performance is excellent.

Best budget option for university projects
My professor recommended this specific board for our embedded systems course. It handles complex tasks like PWM generation and interrupt handling without breaking a sweat. Highly recommended for students.

Perfect for learning ARM architecture
This board is exactly what I needed to start my journey with STM32 microcontrollers. The pinout is clearly labeled, and it works flawlessly with the Arduino IDE using the STLink programmer. Great value for the price.

Great for custom PCB prototypes
I bought five of these to use as the brain for my small robot projects before designing a custom PCB. The form factor is compact, and the processing power is more than enough for motor control and sensor reading.
Q: Is this board compatible with the Arduino IDE?
A: Yes, you can program this board using the Arduino IDE. You will need to install the 'STM32duino' board package via the Board Manager and select the appropriate generic STM32F103C8 variant.
Q: Can I program this using an ST-Link V2 debugger?
A: Yes, absolutely. This board features the standard SWD interface pins (GND, CLK, DIO, 3.3V) which are fully compatible with ST-Link V2 and V3 programmers/debuggers.
Q: Does this board come with pre-soldered pin headers?
A: No, this is a core board intended for integration or prototyping. The pins are not pre-soldered, giving you the flexibility to solder straight headers, right-angle headers, or wires depending on your project needs.
Q: Does this board have a built-in USB-to-Serial converter?
A: No, this is a minimum system board and does not include a USB-to-UART bridge chip. To communicate via USB serial, you will need an external USB-to-TTL adapter connected to the USART pins.
Q: What is the maximum input voltage for the VIN pin?
A: While the microcontroller operates at 3.3V, the onboard regulator typically accepts an input voltage between 3.3V and 5V on the 5V pin. Please do not exceed 5V to avoid damaging the regulator or the chip.
