Arduino is the development board loved by many people who deal with electronics. As you develop projects with Arduino and learn new information, you will notice that Arduino is insufficient. When you realize that it is slow in industrial works, you will start to research and enter alternative card research. You will notice that the solution is stm based development boards. That's why the Stm32f103 is just right for you. Arduino is Nano sized board, but it has more pin output than Arduino. Thanks to the integrated on it, it can do multiple jobs very quickly. That's why we made a special project development set for the STM32F103C8T6 board.
