USB (Pins 1, 3, 5, 7, 9)
Pin Name Pin Number Signal Direction Description
USB_VBUS 1, 3 In 5 V tolerant power Supply VBUS line;
Used only as a USB sense, not for powering the module.
(optional connection)
USB_DP 5 Analog I/O 5 V tolerant data plus pin in USB
USB_DM 7 Analog I/O 5 V tolerant data minus pin in USB
ID_USB 9 Analog I/O 5 V tolerant ID line, it defines the type of
device connected to the phone’s USB
port;
And also the default state (host / device) at the cable con-
nection;
The transceiver senses the voltage of this pin to determ-
ine if the pin is either floating (typical),grounded or res-
istively connected to ground (102 kW, 200 kW, 440 kW);
This is for Novatel Wireless M2M Debug only
