The HK32F103C8T6 Minimum System Board is a compact ARM-based development module built around the HK32F103C8T6/STM32F103C8T6 microcontroller featuring a 32-bit ARM Cortex-M3 core operating at up to 72 MHz. It integrates 64 KB Flash memory, 20 KB SRAM, and supports a supply voltage range of 2.0–3.6 V. The board includes an external high-precision 8 MHz crystal and a 32.768 kHz RTC crystal, along with onboard POR/PDR reset circuitry for stable initialization. All I/O pins are fully broken out to dual-row headers, enabling access to USART, SPI, I²C, CAN, USB-FS, timers, and 12-bit ADC channels. A micro-USB interface provides convenient 5 V power input and communication, while SWD pins enable real-time debugging and firmware programming.

Designed for embedded development, education, and rapid prototyping, the board offers electrical compatibility with STM32-class tools, robust peripheral support, stable timing sources, and a minimal yet complete hardware environment ideal for ARM-Cortex-M3 application design.Note : Actual product may vary in terms of tact switch button .
