I/O
Pin for the data line of the I2C interface, which
must be connected to a 4.7 kΩ pull-up resistor.
This pin can also be used as the common I/O
interface.
5 B I/O
Common I/O interface, which can be used for
PWM output of the LED driver. It controls the blue
LED by default.
6 G I/O
Common I/O interface, which can be used for
PWM output of the LED driver. It controls the
green LED by default.
Intelligent low-power sensors
