STM32F103C8T6 Minimum Development Board (Supports Type-C Serial Port Download)

This project references several similar projects on open-source platforms and modifies existing materials, while also incorporating personal ideas. Its purpose is to facilitate exchange and learning.
Project features include
: 1. Type-C serial port download (referencing mature open-source projects);
2. External 5V power supply to prevent flow into the computer's USB port
; 3. Foolproofing (preventing high voltage and high current from incorrect power supply insertion, short circuits, etc.);
4. An OLED screen interface with an IIC interface on the minimum development board (referencing a mature open-source project);
5. All component power supply pins are handled with capacitors,
etc.
Project parameter example
: Figure 1 -- Power circuit:
uses a TYPE-C-16P interface as the power supply interface.
Example Figure 2 (handle design referenced from a mature project on this platform) .
Shortcomings:
1. The 4-layer board design undoubtedly increases cost
; 2. There are many components near the chip, which increases the difficulty of soldering the main chip last
; 3. This is my first open-source project, so details may not be fully explained.
Finally, thanks to LCSC for providing the platform for learning.
