Specifications

Working Principle

The STM32F103C8T6 acts as the main processing unit of the development board. It executes firmware stored in its Flash memory and uses SRAM for temporary data and program operation.

The microcontroller can be programmed and debugged through the SWD interface. The onboard crystal provides the clock signal required for microcontroller operation.

The Mini USB interface can be used to provide power to the board and for USB communication. External components such as sensors, displays, motors, LEDs, and other peripherals can be connected to the available I/O pins for developing customized embedded applications.

Debugging and Programming

The board supports Serial Wire Debug (SWD), providing a compact interface for programming, debugging, and firmware development.

SWD can be used with compatible STM32 programming/debugging tools to:

• Upload firmware
• Debug programs
• Set breakpoints
• Monitor program execution
• Troubleshoot embedded applications

USB Interface

An onboard Mini USB connector provides convenient connectivity for development.

It can be used for:

• Board power supply
• USB communication
• Development and testing

A suitable USB connection and compatible software/firmware are required for USB communication applications.

Clock and Reset

The board uses a 4–16MHz crystal as its external clock source. The STM32F103C8T6 can use the clock system to achieve its specified operating frequency.

Reset functionality includes Power-On Reset (POR) and Power-Down Reset (PDR), helping the microcontroller start and operate correctly during power-state changes.

Design and Construction

The STM32F103C8T6 development board uses a compact minimum-system design with a footprint of approximately 5.3cm × 2.2cm. Its small size makes it convenient for embedded prototypes, educational projects, and custom electronic systems.
