Features and Construction

The board is designed around the STM32F103C8T6 microcontroller, providing all essential components for a functional minimum system. This approach delivers a practical development platform that requires minimal external components to begin programming and testing.

Material and Build

The development board is constructed using standard PCB materials with surface-mount components soldered to provide reliable electrical connections. The STM32F103C8T6 microcontroller is the central component, surrounded by necessary supporting circuitry including power regulation, clock generation with a 4-16MHz crystal oscillator, and the Mini USB connector. This construction provides a stable platform for development without requiring additional hardware assembly.

Size and Practical Fit

With dimensions of 5.3cm by 2.2cm, this development board offers a compact form factor suitable for integration into prototype enclosures or for use in educational settings where bench space may be limited. The small size does not compromise functionality, as all essential components for the minimum system are included. This makes it particularly useful for embedded projects where final product size is a consideration during the development phase.

Uses and Placement

This development board serves multiple purposes across educational, hobbyist, and professional prototyping environments. Its complete minimum system design makes it immediately usable upon receipt, requiring only connection to a computer for programming.

Event or Professional Use

In professional settings, the board can serve as a rapid prototyping platform for evaluating STM32F103C8T6 microcontroller capabilities before committing to custom PCB design. The integrated Mini USB interface simplifies connection to development tools, while the SWD debug mode support enables efficient programming and debugging workflows. The 72MHz Cortex-M3 CPU, combined with 64KB Flash and 20KB SRAM, provides sufficient resources for developing and testing moderate complexity embedded applications.

Everyday Home Use

For hobbyists and students, this board offers an affordable way to explore ARM microcontroller programming without investing in expensive development kits. The included USB functionality means no additional power supplies or programmers are needed to begin working with the board. The comprehensive documentation available for the STM32F103 series, combined with this physical hardware platform, creates a practical learning environment for embedded systems education and personal projects.

Benefits and Buying Value
