6 SCHEMATICS
Above is a schematic on EV3419A. This is the factory preset when receiving the part.
For other options, please refer to the following table:
R4, R5: Install ~4.7KΩ as the I2C pull-ups if using I2C mode and there is no I2C pull-ups
installed. (DNI by default)
Note: It is recommended not to install more than one pull-ups per I2C bus.
R6: Install ~4.7KΩ pull-up resistor if setting the sensor interrupt pin to open-drain. (DNI by default)
R7: Sensor’s driving current can be measured by putting an ammeter in place of R7.
The physical location of the resistor is in the diagram in Section 8.
