STM32F103C8T6 Minimum System Board

Overview

Introduction:
1. Download and debugging only support SolidWorks (SW) mode.
2. All usable I/O ports are exposed.
3. One 5V, three 3.3V, and five GND pins are exposed, solving the problem of insufficient GND during use.

Precautions:
1. The currently used 49SMD oscillator is prone to cold solder joints; caution is advised. You can replace it with a through-hole or 3215 package crystal oscillator.
2. Please confirm the required load capacitance of your crystal oscillator component.
