3 System Block Diagram
An example of a PCIe M.2 Module system-level block diagram for an embedded application is shown in
Figure 1.
Required connections:
VCC and GND are required to power the PCIe M.2 Module.
RF pin must be connected to the OEM antenna.
USB 2.0 provides host communications to control the operation of the PCIe M.2 Module.
Recommended connections:
LED1#: This signal is used to allow the add-in card to provide status indicators via LED devices that will
be provided by the system.
W_DISABLE1# : This signal allow users to disable, via a system-provided switch, the add-in card’s radio
operation in order to meet public safety regulations or when otherwise desired.
FULL_CARD_POWER_OFF# : This signal is an Active Low input that is used to turn off the entire module.
RESET#: This pin is active, the modem will immediately be placed in a Power On reset condition.
Optional connections:
CONFIG0-4: These signals provide the means to indicate the specific configuration of the module as
well as indication of whether a module is present or not.
(The PCIe M.2 Module default setting: CONFIG_0, 3 N/A, CONFIG_1, 2 Ground.)
