Native USB support for implementing Human Interface Devices (HID) or Virtual COM Ports (VCP).
Up to two SPI interfaces operating up to 18 Mbit/s in master or slave modes. I2C: Up to two SMBus-compatible interfaces. A high-level, highly portable API that simplifies hardware
The STM32F103 family (often represented by its flagship development board, the "Blue Pill" featuring the STM32F103C8T6) uses a highly structured memory and bus architecture. Memory Layout

The NVIC provides low-latency interrupt handling, which is critical for real-time systems. It manages up to 43 maskable interrupt channels and features 16 programmable priority levels. This ensures that time-sensitive tasks, such as safety-critical sensor readings, preempt lower-priority background routines. 2. General-Purpose Input/Output (GPIO)
We hope that this article and PDF guide have provided a comprehensive introduction to the STM32F103 ARM microcontroller and embedded systems. We encourage readers to explore the topic further and to start developing their own embedded systems using the STM32F103 ARM microcontroller.
