STM32F103C8/C6T6 minimum system board

STM32F103CX series smallest system board

Highlights:

The four horizontal pin headers on the front are the download ports. The pin order is the same as that of the smallest system board sold on the market, which are 3V3, SWDIO, SWCLK, and GND;

The four horizontal pin headers on the back are serial port 1 interfaces, which are: 5V, RX, TX, and GND;

It has three indicators: 3V3 power indicator, PC13 pin, TX serial port (it will flash when sending data);

Using a small-sized crystal oscillator, the integration level is higher;

It adopts Type-C interface and is connected to the microcontroller DP and DM. It retains the USB function and can communicate with the computer via USB;

Using mini DIP switch, you can easily switch between BOOT0 and BOOT1 status;

I made it myself and used it for daily debugging. It has been used for 1 year and all functions are normal;

This minimum system board can be applied to STM32F103C8T6, STM32F103C6T6, STM32F030C8T6, STM32F030C6T6 and other chips. It can be replaced as long as the pins are the same.

The overall appearance is beautiful and the performance is powerful!

The demo program turns on the PC pin light and sends data through the serial port every few ms.
