Direct USB connection to PC without debugger or USB-TTL module will not be recognized due to MCU USB protocol requirements.
STM32F103C8T6 main chip with 8MHz crystal oscillator.
Internal PLL supports up to 72MHz system clock.
Both have Cortex-M3 core, 72MHz max frequency, LQFP48 package, SWD debug interface, USB 2.0 support.
STM32F103C6T6 can replace STM32F103C8T6 in applications not requiring Timer 4 or UART3.
ISP programming mode requires holding BOOT key during power-up.
Product is shipped sealed in anti-static high-temperature bags.
Testing performed on test fixture before shipment.
STM32F103 core development board (C8T6 or C6T6 version)
Documentation with wiring diagrams for debugger and USB-TTL connections
Always use CMSIS-DAP debugger or USB-TTL module for programming.
Follow wiring instructions carefully to avoid device recognition issues.
For debugging and development, CMSIS-DAP is recommended due to combined download and debug capabilities.
