STM32 card is a development board called Blue Pill, it is low cost that incorporates the high-performance ARM®Cortex-M3 32-bit RISC core, this card is suitable for starting projects on the STM32 microcontroller. It comes with male – male header terminals that you can solder yourself.

What is StM32F103C6T6 Blue Pill Card for?

STM32F103C6T6 is a very powerful microcontroller and with 32-bit CPU, it can easily surpass Arduino UNO in performance. To program this board you have to use an ST-LINK V2 programmer since this board does not incorporate a programmer, it needs an external one, there are different ways to program it either with STM32 IDE or even with Arduino IDE.
