Exceeded expectations

Using this for a drone flight controller prototype. The ADC readings are stable, and the timer interrupts are precise. Very happy with this purchase.

Perfect for industrial prototyping

This board is exactly what I needed for my motor control project. The STM32F103RCT6 handles the PWM signals flawlessly, and the pinout is clearly labeled. Build quality feels robust enough for bench testing.

Reliable minimal system

I've ordered five of these for a custom HMI interface. All boards booted up immediately without issues. The voltage regulator stays cool even under moderate load. Highly recommended for production prototypes.

Great value for learning embedded systems

Excellent board for university projects. It works seamlessly with STM32CubeIDE. Only giving 4 stars because the documentation link on the box was broken, but I found the datasheet online easily.

Easy to flash and debug

Connected via ST-Link V2 without any driver headaches on Windows 10. The reset and boot jumpers are easy to access. Perfect size for fitting into small enclosures.

Solid performance, missing headers

The chip performance is top-notch for the price point. My only critique is that it doesn't come with pre-soldered pin headers, so you need to solder them yourself if you want to use it on a breadboard.

5 FAQ

Q: Are the pin headers pre-soldered on the board?

A: No, the board is shipped without pre-soldered headers to keep costs low and allow flexibility for different mounting options. You will need to solder your own headers if required.

Q: What is the operating temperature range for industrial use?

A: The STM32F103RCT6 chip supports an operating temperature range of -40°C to +85°C, making it suitable for most industrial control environments.

Q: Does this board come with a built-in programmer or do I need an external ST-Link?

A: This is a minimal system board and does not include a built-in programmer. You will need an external debugger/programmer such as an ST-Link V2 or J-Link to flash code and debug.

Q: Can this board be powered directly via the USB port?

A: Yes, the board can be powered via the Micro-USB port (5V). It also features a VIN pin for external power supply input ranging from 5V to 9V.

Q: Is this compatible with the Arduino IDE?

A: Yes, you can use this board with the Arduino IDE by installing the appropriate STM32 core packages (e.g., STM32duino). However, for advanced features, we recommend using STM32CubeIDE or Keil.
