Explore the capabilities of the STM32F103C8T6 Development Board, designed for advanced microcontroller enthusiasts and engineers. This board features the powerful ARM -M3 architecture, ensuring high performance and reliability for your projects. Equipped with an original STM32F103C8T6 chip and a CH340 USB-to-serial converter, this development board provides a robust platform for programming and experimentation. Its minimal system design facilitates easy integration into larger projects or serves as a great starting point for learning the intricacies of ARM-based systems. TYPE-C USB:Power input or USB /serial port(CH340N) Buttons:(reset button),BTO(boot mode selection button) LED:PWR(Power indicator),C13(user control indicator,PC13 control LED cathode) ABOUT TYPE-C PORT FUNCTION SELECTION: the core board pursues a small size for a single TYPE-C port design,and the USB function and serial port function are mutually exclusive design,when welding U2 (CH340N) without welding R4 and R5,port C is used as a serial communication function. When U2(CH340N) is not welded to R4 and R5,port c is used as a USB communication function. About TYPE-C port CC port hardware design CC1 and CC2 pins are suspended: Only USBA to TYPE-C data cable can be used for power supply. Pull-down 5.1K resistors with short CC1 and CC2 pins: Use both a fast charging source and an EMARK core The -port cable of the chip not be powered, and the rest can be powered normally. CC1 and CC2 pin pull-down 5.1K resistors respectively: standard design, power supply, recommended. Serial download Enter BOOT mode: Hot enter: Hold down the reset and BOOT buttons at the same time, release the reset button for about 1 second, and then release the BOOT Press the button to enter the BOOT download mode. Coldenter: Hold down the BOOT button, plug in the USB power supply for about 1 second, and then release the BOOT button BOOT Download mode.
