Pin	Name	STM32	Description
1	VCC2V8.	Vcc	Connected to the output of the U9 regulator (2.8V). This source could provide approximatively 100mA to the extension board.
2	GND	GND	Ground
3	CX_I2CSCL.	PB.6	Can be used either as a standard GPIO or considered as an alternate function: - I2C1_SCL - TIM4_CH1 - USART1_TX (if remapped)
4	CX_I2CSDA.	PB.7	Can be used either as a standard GPIO or considered as an alternate function: - I2C1_SDA - TIM4_CH2 - USART1_RX (if remapped)
5	AUDIO_SPI_MISO	PB.14	Can be used either as a standard GPIO or considered as an alternate function: - SPI2_MISO - USART3_RTS - TIM1_CH2N Note that SPI2 is also connected to the audio device for recording audio data from the microphone. This feature must be disabled when SPI2 is used with the extension board.
6	AUDIO_I2S2_SD	PB.15	Can be used either as a standard GPIO or considered as an alternate function: - SPI2_MOSI- TIM1_CH3N Note that SPI2 is also connected to the audio device for recording audio data from the microphone. This feature must be disabled when SPI2 is used with the extension board.
7	AUDIO_I2S2_SCK	PB.13	Can be used either as a standard GPIO or considered as an alternate function: - SPI2_SCK - USART3_CTS - TIM1_CH1N Note that SPI2 is also connected to the audio device for recording audio data from the microphone. This feature must be disabled when SPI2 is used with the extension board.
8	AUDIO_I2S2_WS	PB.12	Can be used either as a standard GPIO or considered as an alternate function: - SPI2_MOSI - TIM1_CH3N(6) Note that SPI2 is also connected to the audio device for recording audio data from the microphone. This feature must be disabled when SPI2 is used with the extension board.
9	CX_CANH		Connected to the CAN transceiver. When the CAN transceiver is not soldered, these pins could be easily connected to PD.2-PD.3 on the STM32 by shortcutting the signals on the footprint of the CAN transceiver.
10	CX_CANL
11	CX_ADC1	PC.4	Can be used either as a standard GPIO or considered as an alternate function: ADC12_IN14
12	CX_ADC2	PC.5	Can be used either as a standard GPIO or considered as an alternate function: ADC12_IN15
13	CX_ADC_TIM	PB.0	Can be used either as a standard GPIO or considered as an alternate function: - ADC12_IN8 - TIM3_CH3 - TIM1_CH2N (if remapped)
14	CX_USART_CTS	PA.0	PA0/WKUP/ADC IN0Can be used either as a standard GPIO or considered as an alternate function: - WKUP - USART2_CTS - ADC12_IN0 - TIM2_CH1_ETR
15	CX_USART_RTS	PA.1	Can be used either as a standard GPIO or considered as an alternate function: - USART2_RTS - ADC12_IN1 - TIM2_CH2
16	CX_USART_TX	PA.2	Can be used either as a standard GPIO or considered as an alternate function: - USART2_TX - ADC12_IN2 - TIM2_CH3
17	CX_USART_CK	PA.4	Can be used either as a standard GPIO or considered as an alternate function: - SPI1_NSS - USART2_CK - ADC12_IN4
18	CX_USART_RX	PA.3	Can be used either as a standard GPIO or considered as an alternate function: - USART2_RX - ADC12_IN3 - TIM2_CH4
19	VCC_EXT.		Could be used to reload the battery (input voltage in the [4.5-5V] range)
20	GND	GND	Ground
