SB16 ON STM32 PB6 is connected to CN4 pin 7 for I2C SDA support onArduino Nano A5. In such case STM32 PB6 does not supportArduino Nano D5 and PA6 must be configured as input floating
SB16 OFF CN4 pin 7 is used as Arduino Nano analog input A5 without I2Csupport and CN3 pin 8 is available as Arduino Nano D5.
同理SB18 ONSTM32 PB7 is connected to CN4 pin 8 for I2C SCL support onArduino Nano A4. In such case STM32 PB7 does not supportArduino Nano D4 and PA5 must be configured as input floating.
OFF CN4 pin 8 is used as Arduino Nano analog input A4 without I2Csupport and CN3 pin 7 is available as Arduino Nano D4.
