Remarks
USB interface for AT commands, data communication, FOAT,
FW update by u-blox EasyFlash tool and diagnostic.
90 nominal differential impedance (Z
30 nominal common mode impedance (Z
Pull-up or pull-down resistors and external series resistors as
required by the USB 2.0 specifications [9] are part of the USB
pin driver and need not be provided externally.
If the USB interface is not used by the Application Processor,
