Pinout

Pin Name Type Function
1 PA2 bidirectional GPIO PA2. Alt: USART1_TX/USART2_TX, TIM1_CH2N, MCO, SPI1_MISO, COMP2_OUT. Additional: ADC_IN2, COMP2_INM. 5V-tolerant COM port.
2 PA3 bidirectional GPIO PA3. Alt: USART1_RX/USART2_RX, TIM1_CH3, MCO, SPI1_MOSI, EVENTOUT. Additional: ADC_IN3, COMP2_INP. 5V-tolerant COM port.
3 PA4 bidirectional GPIO PA4. Alt: SPI1_NSS, USART1_CK, TIM14_CH1, USART2_CK. Additional: ADC_IN4. 5V-tolerant COM port.
4 PA5 bidirectional GPIO PA5. Alt: EVENTOUT, RTC_OUT, TIM3_CH3, USART2_TX, SPI1_SCK, LPTIM_ETR. Additional: ADC_IN5. 5V-tolerant COM port.
5 PA6 bidirectional GPIO PA6. Alt: EVENTOUT, TIM3_CH2, USART2_RX, MCO, SPI1_MISO, TIM3_CH1, TIM1_BKIN, TIM16_CH1. Additional: ADC_IN6. 5V-tolerant COM port.
6 PA7 bidirectional GPIO PA7. Alt: EVENTOUT, COMP1_OUT/COMP2_OUT, USART1_CK, RTC_OUT, SPI1_MOSI, TIM3_CH2, TIM1_CH1N, TIM14_CH1, TIM17_CH1. Additional: ADC_IN7. 5V-tolerant COM port.
7 VSS power_in Ground reference (0 V) for the digital and analog supply. Tie to system GND with a low-impedance return.
8 PA12 bidirectional GPIO PA12. Alt: EVENTOUT, USART1/USART2 flow-control, TIM1 channels, SPI1 signals, I2C_SDA. 5V-tolerant COM port.
9 VCC power_in Main supply pin, 1.7 V to 5.5 V. Decouple with 100 nF close to the pin plus one bulk cap.
10 PA13/SWDIO bidirectional SWD data (SWDIO) after reset; can be reassigned to GPIO PA13 with alternate functions (IR_OUT, USART1/2, SPI1, TIM1, COMP2_OUT).
11 PA14/SWCLK bidirectional SWD clock (SWCLK) after reset; can be reassigned to GPIO PA14 with alternate functions (USART1_TX, USART2_TX, TIM1_BKIN).
12 PB5 bidirectional GPIO PB5. Alt functions include SPI1_MOSI, USART1/USART2 signals, TIM3_CH2, TIM16/TIM17 channels. 5V-tolerant COM port.
13 PB6 bidirectional GPIO PB6. Alt functions include I2C_SCL, USART1_TX, TIM1_CH3, SPI1_MISO. 5V-tolerant COM port.

15 PF4/BOOT0 bidirectional Boot mode select (BOOT0) sampled at reset; also usable as GPIO PF4. BOOT0 combined with the nBOOT1 option byte selects main flash, system memory, or SRAM boot.
16 PF0/OSC_IN bidirectional HSE crystal input (OSC_IN); also usable as GPIO PF0 with alt USART1_RX/USART2_TX, TIM14_CH1, I2C_SDA.
17 PF1/OSC_OUT bidirectional HSE crystal output (OSC_OUT); also usable as GPIO PF1 with alt USART1_TX/USART2_RX, I2C_SCL, SPI1_NSS, TIM14_CH.
18 PF2/NRST bidirectional Active-low reset input with internal weak pull-up (RST-type pad). Can be optionally reconfigured as GPIO PF2 via option bytes; alt: MCO.
19 PA0 bidirectional GPIO PA0. Alt: USART1_CTS, USART2_CTS, COMP1_OUT, TIM1_CH3, TIM1_CH1N, SPI1_MISO. Additional: ADC_IN0, COMP1_INM. 5V-tolerant COM port.
20 PA1 bidirectional GPIO PA1. Alt: USART2_TX/RX, IR_OUT, SPI1_SCK, USART1/2 RTS, EVENTOUT, TIM1_CH4, TIM1_CH2N, SPI1_MOSI. Additional: ADC_IN1, COMP1_INP. 5V-tolerant COM port.
