Specifications of STM32F103C8T6:

Operating voltage: 2.7V to 3.6V

CPU Frequency: 72 MHz

Number of GPIO pins: 37

Number of PWM pins: 12

Analog Input Pins: 10 (12-bit)

USART Peripherals: 3

I2C Peripherals: 2

SPI Peripherals: 2

Can 2.0 Peripheral: 1

Timers: 3(16-bit), 1 (PWM)

The development board can be easily programmed using the Arduino IDE. But if you want to explore the complete STM32 development boards, you can also use the STM32Cube and other development environments offered by ST Microelectronics. You can also use Keil, IAR workbench, Atollic TrueStudio, MicroC Pro ARM, Crossworks ARM, Ride 7, PlatformIO+STM32 etc. to program the board. The hex file of a program can be uploaded using a single wire interface module (SWIM) or by using JTAG/ serial wire debugging (SWD).

If you want to program your STM32 MCU using a USB cable(without FTDI board) on an Arduino IDE, you need to get an Arduino compatible bootloader for the STM32 and then you can flash it into the STM32 board. Once the STM32 is flashed with the Arduino compatible bootloader, you can directly program the STM32 using Arduino IDE without the FTDI board and you don’t have to press the reset button when you upload a code.
