Frequently Asked Questions

Q: What is the difference between the STM32F103C6T6 and STM32F103C8T6 development boards?

A: Both boards share the same ARM Cortex-M3 core and minimum system layout, but they differ in memory. The STM32F103C6T6 offers 32KB of Flash and 10KB of RAM, while the STM32F103C8T6 provides 64KB of Flash and 20KB of RAM. Choose the C8T6 for more memory-intensive applications.

Q: What software can I use to program the STM32 Minimum System Development Board?

A: This board is compatible with Keil MDK and IAR Embedded Workbench. You can upload firmware via a J-Link debugger over the SWD interface or use the built-in USART1 serial bootloader with a USB-to-serial adapter for a cost-effective setup.

Q: Is this board compatible with Arduino?

A: Yes — while the board runs on the STM32 platform rather than the traditional AVR-based Arduino, it is compatible with Arduino-style workflows using the STM32duino core, and it works well alongside standard Arduino modules, sensors, and peripherals.

Q: Does the board come pre-loaded with any firmware?

A: The board comes with owner-provided test and debugging procedures pre-loaded, so you can verify functionality immediately. If you encounter any issues or require custom firmware, contact the seller for support.

Q: What voltage does the onboard regulator supply?

A: The onboard RT9193 voltage regulator provides a stable 3.3V output with a maximum current of 300mA, which is sufficient for most common peripherals and sensors used in embedded projects.
