Coin-sized STM32F103C8T6 minimum system board

 
Overview

The smallest STM32F103C8T6 system board is only the size of a coin.
Electronic enthusiasts are familiar with the STM32F103C8T6. The smallest C8T6 system board on the market has the problem of large size, so I drew a 25*25-sized STM32F103C8T6 smallest system board.
The relevant circuit design is not repeated here. The linear voltage regulator uses RT9013-33, the BOOT selection is connected by welding through the bottom pad, and ST-Link is used for burning.
The smallest system of this design includes the reset circuit, crystal oscillator circuit, power pin header and other peripheral circuits necessary for the work of the microcontroller, and all the commonly used pins are brought out to facilitate R&D personnel to embed this solution into the development.
Resistors and capacitors are all packaged in 0603 for easy welding.

There may be problems with the design, and I sincerely ask for your criticism and correction.
