Description

The WeAct Studio STM32F103C8T6 Bluepill Plus is a high-quality minimum system board built around the industry-standard STM32F103 ARM Cortex-M3 core. It delivers 1.25 DMIPS/MHz performance with zero wait-state memory access, enabling efficient execution of real-time control algorithms and data processing tasks. The board is engineered for stability with an 8 MHz system crystal and a 32.768 kHz RTC crystal for precise timing operations.

Designed for developers and makers, it provides a full-featured GPIO breakout via two 20-pin headers and a 4-pin SWD programming header, facilitating seamless connection to sensors, displays, and communication modules. The inclusion of a dedicated SPI Flash chip offers additional storage for data logging, firmware updates, or file systems. Its USB-C interface simplifies the development workflow, supporting direct programming via ST-Link/V2 and providing a clean 5V power input.

Key Features

  • High-performance 32-bit ARM Cortex-M3 core operating at up to 72 MHz clock speed.
  • Ample memory with 64 KB of embedded Flash and 20 KB of SRAM for application development.
  • Integrated SPI Flash memory (U3) accessible via GPIO pins for expanded storage needs.
  • Stable clocking system with an 8 MHz HSE crystal and a low-power 32.768 kHz LSE crystal for RTC.
  • Modern USB Type-C connector for robust data connectivity, debugging, and board power.
  • Comprehensive I/O access through dual 20-pin headers, exposing all microcontroller GPIOs.
  • Onboard status LEDs: a blue user LED (PB2) and a red power indicator for immediate visual feedback.
  • Compact and breadboard-friendly design, making it ideal for prototyping and embedded system integration.

Applications

  • Prototyping embedded control systems for robotics, drones, and motor control.
  • Developing industrial automation devices, PLCs, and sensor data loggers.
  • Building educational tools and kits for learning ARM Cortex-M architecture and real-time operating systems (RTOS).
  • Creating IoT node devices when paired with external Wi-Fi, Bluetooth, or LoRa communication modules.
  • Designing human-machine interfaces (HMI) and data acquisition systems.

Frequently Asked Questions

How do I program the WeAct Studio Bluepill Plus board?

You can program it using an ST-Link/V2 debugger connected to the onboard 4-pin SWD header (SWDIO, SWCLK). Configure your IDE (STM32CubeIDE, Keil, or PlatformIO) to target the STM32F103C8T6 device. The USB-C port provides power and can be used for Virtual COM Port (VCP) communication if the appropriate bootloader is flashed.

What is the purpose of the onboard SPI Flash (U3) chip?

The SPI Flash provides additional non-volatile storage separate from the microcontroller's internal Flash. You can use it to store log files, firmware updates, graphics assets, or configuration data. It is accessed via the assigned GPIO pins: PA4 (CS), PA5 (SCK), PA6 (MISO), and PA7 (MOSI). You must manage the chip select line in your firmware.

What is the power supply requirement for this development board?

The board is typically powered via the USB Type-C connector, which supplies 5V. The onboard voltage regulator steps this down to the 3.3V required by the STM32 microcontroller. Ensure your USB port or external adapter can provide sufficient current (typically 100-500mA) for your application and any connected peripherals.
