Summary STM32 Blue Pill Expansion Board
This is the expansion board for our Generic STM32 (Blue Pill) Development board. All the USART, SPI and I2C pins are rearranged for easy usage. This board has got the standard FTDI board connector so that a FTDI basic board or a FTDI USB to Serial converter can be directly connected to for easy programming. The analog pins (ADC) and the PWM pins as well as the 5 volt tolerant pins of the Blue Pill board has been also marked. The DC jack can be used to connect power from a battery or an adapter to this board. The on board voltage regulator converts the input voltage to 3.3 volt that is needed to run the BluePill board.
