STM32F103C8T6

1. Components named in the format "NC_value" are not solderable. 2. Because the components are compiled from multiple schematics, the same component may be listed separately in the BOM due to different manufacturers. When organizing the BOM, it is necessary to exclude manufacturer classifications and organize the material quantities according to package and component value. 3. Because the power supply is only an LDO and there is no reserved interface for an external DC-DC converter module, the external power is limited. 4. Most of the hardware peripheral functions of the STM32F103C8T6 are brought out in a modular form, including one CAN, one UART, one I2C, one SPI, one SWDIO, several external interrupt interfaces, and three complementary outputs of TIM1, totaling 6 ports. 5. The current limiting resistors for the two power indicator lights can be adjusted according to the LEDs selected (5~100k).
6. If the VBAT pin is not connected to an external power supply, it needs to be shorted to 3V3 with a jumper cap.
7. The three jumper caps can be configured directly according to the cover diagram.
8. There is only one capacitor on the back. In actual testing, there was no visible impact when that capacitor was not soldered.
