GD32103C-START is a comprehensive, easy-to-use and flexible development platform based on GD32103C microcontroller, which includes the STM32F103C8T6 ARM Cortex-M3 microcontroller, various development tools and accessories. This ARM Cortex-M3 microcontroller supports a wide range of applications, such as motor control, user interface, and low-power handheld device control. This platform includes an STM32F103C8T6 microcontroller mounted on a 200-pin board, with six major peripheral components: a built-in serial communication interface (USART), two 12-bit ADC, two SPI/I2C, 12 PWMs, and two USARTs. The platform also includes a series of complementary devices, such as external usb-to-serial converter, an I2C Flash programmer, an ST-Link/V2 debugger and programmer, and an enclosed case for the board. The platform utilizes the integrated on-chip debugging and programming capabilities of the ARM processor and contains an integrated full-featured debugging environment. This platform is used by developers to quickly design and test applications in areas such as consumer electronics, computers, machine tools, and other industrial automation applications.
