M Addr.
Set the SDO_AG and SDO_M to set the
accel/gryo and mag I2C addresses:
JP1 pulls the SDA and SCL data lines
high through R1 and R2. To disable pull-up
resistors, cut traces on both sides.
JP2 sets the I2C address for the
accelerometer and gyroscope.
JP3 sets the I2C address for the
magnetometer.
