NUCLEO-L432 nucleo 遇到了问题大神科普
焊盘掉了一个为什么是通的?有什么意义科普一下?PA6和PB6是通的.0欧电阻是焊上的
为什么这么设计?
自古二楼归楼主.

善于发现问题
SB16 ONSTM32 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.

点个赞.手工去掉电阻,我们不需要anduino 点个赞.手工去掉电阻,我们不需要anduino
