STM32F103C8T6 CH340 Development Board Original Chip Microcontroller Core Board ARM Architecture Minimum System Correx-M3 Beskrivelse

Explore the capabilities of the STM32F103C8T6 Development Board, designed for advanced microcontroller enthusiasts and engineers. This board features the powerful ARM Cortex-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:RST(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 selected 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 double C-port cable of the chip will 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.
