STM32F103C6T6 ARM STM32 Minimum System Development Board — Clone Chip
This minimum system board runs the STM32F103C6T6 ARM Cortex-M3 at 72MHz with 32KB flash and 10KB SRAM on a compact board with a single USB Micro-B connector for programming. It is programmed via STM32CubeIDE, the Arduino IDE (STM32duino), or PlatformIO using either a serial bootloader (built-in) or SWD via ST-Link V2. The BOOT0 jumper selects between normal run mode and serial bootloader mode for driver-free flashing.
