STM32F103C8T6 core board

Overview

STM32F103C core board

The commonly used DIP40 pin is used, and the programming port line sequence is MuseLab's DAP-Link interface, SWD mode.
2 user LEDs, 2 user buttons, and 1 reset button.
BOOT uses switches instead of pin headers, eliminating the trouble of pulling out jumper caps and the difficulty of dialing dial switches.

The programming port is changed to a curved plug, the Type-C interface is not blocked by pressing the switch
, the CC foot strap has a 5.1k pull-down, the C2C line can also be used with
high-power LDO, the pad is punched, the back window is opened, and the USB interface is used to assist heat dissipation. Remember to solder the window area under the USB interface, otherwise the heat dissipation effect will
be reduced. The crystal oscillator will be a patch, which will reduce the area.
