= Development and Programming =
The board supports multiple development environments including STM32CubeIDE, Keil MDK, IAR EWARM, and Arduino IDE. Programming requires an ST-Link V2 programmer connected via SWD interface. For peripheral configuration, STM32CubeMX provides easy setup.
Use STM32CubeMX for easy peripheral configuration
Select "STM32F103RC" board in Arduino IDE for compatibility
USB port is not for programming use STLink only
Core voltage is 3.3V - do not apply 5V to GPIO
= Troubleshooting =
Board not recognized:
- Use ST-Link V2 programmer for SWD programming
- USB is power only (or USB OTG function) unless CH340 included
- Install STM32CubeProgrammer for firmware upload
Firmware upload fails:
- Check SWD connections (SWCLK, SWDIO, GND, 3.3V)
- Ensure board is powered (3.3V via ST-Link or external)
- Verify correct target MCU selected in IDE
