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.

  • STM32F103C6T6 Cortex-M3 at 72MHz
  • 32KB flash, 10KB SRAM
  • 37 GPIO pins — 10 with ADC, UART, SPI, I2C, CAN
  • USB Micro-B — serial bootloader for driver-free flashing
  • BOOT0 jumper — selects bootloader or normal run mode
  • SWD header — ST-Link V2 debug interface

Best for

STM32 beginner projects, stepping up from Arduino to ARM Cortex-M, USB HID prototypes, and projects needing more processing power than the ATmega328P at a similar price.

Chloe ★★★★★

For the price, getting a 72MHz ARM Cortex-M3 with 32KB flash on such a small board is impressive — it compiled my code without a hitch. Boots up reliably via USART, and the compact layout fits nicely on a breadboard for testing.

Natalie G. ★★★★★

I needed a 72MHz Cortex-M3 for a small project and this board delivers exactly that, with the 32KB flash being plenty for my code. The compact layout made it easy to breadboard and it runs stable at the advertised clock speed.

Emily ★★★★★

Got this to mess around with bare-metal programming and it fits perfectly on a breadboard, which is exactly what I wanted. The 32KB flash is a bit tight if you're used to bigger chips, but for blinking LEDs and learning the registers it's more than enough. Bootloader works fine over the serial pins
