Overview There are two main ways to program the STM32F103C8T6 module, also known as the STM32 Blue Pill: • Serial and USB to TTL converter • ST-Link Tip Sometimes you might find out that the STM32 module you have is not original. And it can’t be programmed through serial. Therefore, we suggest you use ST-Link to program the STM32 Blue Pill. Required Materials Hardware Components STM32F103C8T6 Blue Pill × 1 ST-Link/V2 Programmer × 1 Male to Male Jumper Wire × 1 Software Apps Ar...
