The Blue Pill Board Pinout:
The STM32F103C8T6 MCU offers multiple functions for each pin. It's important to note that certain IO pins are 5V tolerant, allowing seamless connection with 5V-compatible IO devices. Firmware installation can be accomplished either through USART1 using the permanently installed serial bootloader or through SWD with an ST-Link adapter.
During regular operation, the Boot1 jumper (PB2) is available for custom applications. It is recommended to resell the frame of the sensitive USB socket. To avoid a short circuit, it's crucial not to supply power to the board simultaneously via USB and a 5V power source. However, an additional 3.3V supply is acceptable.
