Solder bridges (SB7, SB8, SB9, and SB10) are used to select ADC or I
2
C signals to the ARDUINO
®
connector (CN9) pins 9
and 11.
•
SB10 ON and SB8 OFF: The ADC is connected to the ARDUINO
®
connector CN9 pin 9. SB9 ON and SB7 OFF: The
ADC is connected to the ARDUINO
®
connector (CN9) pin 11 (default configuration).
• SB10 OFF and SB8 ON: I2C_SDA is connected to the ARDUINO
®
connector (CN9) pin 9. SB9 OFF and SB7 ON:
I2C_SCL is connected to the ARDUINO
®
connector (CN9) pin 11.
