Pinout

Pin	Name	Type	Function
1	C1A	passive	Channel 1 capacitor input (analog). Positive terminal of the sensing capacitor for channel 1; connects to the external inductor L / sensing capacitor Cp network.
2	C1B	passive	Channel 1 capacitor ground (analog). Negative/return terminal of the channel-1 sensing capacitor; internally tied to GNDA through the chip in dual-electrode mode.
3	VC	passive	Reference voltage pin for the capacitive AFE. Typically bypassed with an external decoupling capacitor.
4	VT	passive	Temperature-sensing voltage pin (analog). Used together with the on-chip temperature sensor for temperature compensation.
5	RUP	passive	External resistor pin (standard I/O, TC level). Sets the AFE drive/pull-up current via an external resistor to VDD.
6	GND	power_in	Digital ground return, 0 V reference for the digital core and I/O.
7	PA15	bidirectional	General-purpose I/O PA15 (standard TC-level I/O, input tolerant to VDD). Alt functions: SPI1_NSS, TIM1_CH3N, SPI1_MOSI, TIM3_CH3; ADC1_VIN[6] additional analog input.
8	PA2	bidirectional	General-purpose I/O PA2 (standard TC I/O). Alt functions: TIM1_CH2N, SPI1_MISO, TIM3_CH2; ADC1_VIN[5] additional analog input.
9	PA12	bidirectional	General-purpose I/O PA12 (standard TC I/O). Alt function: USART1_TX; ADC1_VIN[3] additional analog input.
10	PA3	bidirectional	General-purpose I/O PA3 (standard TC I/O). Alt functions: USART1_RX, USART2_SCK, SPI1_NSS; ADC1_VIN[2] additional analog input.
11	PA14(NRST)	bidirectional	General-purpose I/O PA14 (standard TC I/O). Alt functions: SWCLK (serial-wire debug clock), USART1_TX, SPI1_SCK. When RCC_SYSCFG SFT_NRST_RMP=1 the pin is remapped as external reset (NRST) and reset low must be held >=4 us.
12	PB0(OSCIN)	bidirectional	General-purpose I/O PB0 (standard TC I/O). Alt function: USART2_SCK; ADC1_VIN[1] additional analog input. Can be configured as the external HSE clock input (OSCIN) up to 48 MHz.
13	PA1	bidirectional	General-purpose I/O PA1 (standard TC I/O). Alt functions: USART1_SCK, USART2_TX, I2C1_SDA, SPI1_MOSI.
14	VDD	power_in	Digital power supply input, 2.5 V to 5.5 V. Feeds the MCU core and digital I/O; decouple locally with a bypass capacitor.
15	PA13	bidirectional	General-purpose I/O PA13 (standard TC I/O). Alt functions: SWDIO (serial-wire debug data), USART1_RX, USART2_RX, I2C1_SCL, SPI1_MISO.
16	PA10	bidirectional	General-purpose I/O PA10 (standard TC I/O). Alt functions: SPI1_MISO, TIM1_CH3, TIM1_CH2, MCO (master clock output), USART1_TX.
17	PA0	bidirectional	General-purpose I/O PA0 (standard TC I/O). Alt functions: SPI1_NSS, USART1_RX, TIM1_CH3N, I2C1_SCL, TIM3_CH3.
18	PA4	bidirectional	General-purpose I/O PA4 (standard TC I/O). Alt functions: TIM1_BKIN, I2C1_SDA, TIM3_CH4.
19	PA5	bidirectional	General-purpose I/O PA5 (standard TC I/O). Alt functions: SPI1_SCK, TIM1_CH1N, I2C1_SCL.
20	GND	power_in	Digital ground return (second GND pin), 0 V reference for the digital core and I/O.
21	VDDA	power_in	Analog power supply input for the capacitive AFE and ADC. Typically tied to VDD through a low-impedance filter; decouple with a local bypass capacitor.
22	GNDA	power_in	Analog ground return, 0 V reference for VDDA / AFE / ADC. Should be joined to digital GND at a single star point.
23	C0A	passive	Channel 0 capacitor input (analog). Positive terminal of the sensing capacitor for channel 0; connects to the external inductor L / sensing capacitor Cp network.
24	C0B	passive	Channel 0 capacitor ground (analog). Negative/return terminal of the channel-0 sensing capacitor; internally tied to GNDA through the chip in dual-electrode mode.
