        However, the STM32F103C8T6 is equipped with only 64kB. Although it seems that majority of Blue Pill boards sold online usually feature 128kB Flash rather than 64kB. Once the compilation is complete (started by clicking on the Build only button in the Compile drop list or by pressing Ctrl+B)...
