Pinout

Pin	Name	Type	Function
1	BOOT0	input	Boot mode selection input; low selects boot from Flash, high selects system memory or SRAM depending on the nBOOT1 bit.
2	PF0/HXT_IN	bidirectional	General-purpose I/O PF0 that also serves as the HXT (4~32MHz crystal oscillator) input.
3	PF1/HXT_OUT	bidirectional	General-purpose I/O PF1 that also serves as the HXT (4~32MHz crystal oscillator) output.
4	NRST	bidirectional	Active-low reset input / internal reset output with a permanent pull-up; after POR exit it must be held for at least 9 ms or the FWDT may be enabled.
5	VDDA	power_in	Analog supply powering the ADC, HRC, HRC14, PLL, POR/PDR and LVD; range from VDD to 5.5V, above 2.4V when the ADC operates.
6	PA0	bidirectional	General-purpose I/O PA0 with USART2_CTS alternate function and ADC_IN0 / WKUP1 special functions.
7	PA1	bidirectional	General-purpose I/O PA1 with EVENTOUT and USART2_RTS alternate functions and ADC_IN1 special function.
8	PA2	bidirectional	General-purpose I/O PA2 with USART2_TX and TIM15_CH1 alternate functions and ADC_IN2 special function.
9	PA3	bidirectional	General-purpose I/O PA3 with USART2_RX and TIM15_CH2 alternate functions and ADC_IN3 special function.
10	PA4	bidirectional	General-purpose I/O PA4 with SPI1_NSS, TIM14_CH1 and USART2_CK alternate functions and ADC_IN4 special function.
11	PA5	bidirectional	General-purpose I/O PA5 with SPI1_SCK alternate function and ADC_IN5 special function.
12	PA6	bidirectional	General-purpose I/O PA6 with SPI1_MISO, TIM3_CH1, TIM1_BKIN, TIM16_CH1 and EVENTOUT alternate functions and ADC_IN6 special function.
13	PA7	bidirectional	General-purpose I/O PA7 with SPI1_MOSI, TIM3_CH2, TIM14_CH1, TIM1_CH1N, TIM17_CH1 and EVENTOUT alternate functions and ADC_IN7 special function.
14	PB1	bidirectional	General-purpose I/O PB1 with TIM3_CH4, TIM14_CH1 and TIM1_CH3N alternate functions and ADC_IN9 special function.
15	GND	power_in	Chip ground pin.
16	VDD	power_in	Digital supply for I/O, regulator and HXT, range 2.0V to 5.5V.
17	PA9	bidirectional	General-purpose I/O PA9 with USART1_TX, TIM1_CH2, I2C1_SCL and CKO alternate functions; I2C port supporting Fast-mode Plus.
18	PA10	bidirectional	General-purpose I/O PA10 with USART1_RX, TIM1_CH3, TIM17_BKIN and I2C1_SDA alternate functions; I2C port supporting Fast-mode Plus.
19	PA13	bidirectional	General-purpose I/O PA13 configured as SWDIO after reset (internal pull-up active), with IR_OUT alternate function.
20	PA14	bidirectional	General-purpose I/O PA14 configured as SWCLK after reset (internal pull-down active), with USART2_TX alternate function.
