FRDM-KL27Z hardware description
This also designed to be compatible with 6-axis (FXOS8700CQ) combination of accelerometer and
magnetometer sensor, if populating the U10 (FXOS8700CQ), and then keep U2 (MAG3310) DNP.
Otherwise, populate U10 (MMA8451) and U2 (MAG3110).
A Freescale MAG3110 low-power, three-axis magnetometer is interfaced through an I
2
C bus and one
GPIO signals as shown in
Table 5
. By default, the I
2
C address is 0x0E .
