Difference between WMI2—W167 to WMIZ2—W167—M1 & WMI2—W167—M2

The 4—pole—MQS connector is basically interface for the external NFC antenna; the WMI2—W167 is very
much the same to WMI2—W167—M1& WMIZ—W167—M2 except the interface to external NFC Antenna.

The interface has been adapted to improve EMC stability.

The difference in the hardware on the main board is documented with enclosed pictures. It shows the
schematics difference. This change also causes a layout change in this area. All other functions and
placements at are identical.

                                                                                                                                              WMI2—W167
