1.General
M320 is built according to the PCI express mini card specification and is an
integrated solution using the notebook’s antenna system. It is designed as an
add-in option for integrators of notebook computers and is comprised of several
component parts:
HSDPA wireless network adapter which is the wireless enabler and circuitry
integrated onto the Mini Card PCB together with its mechanical RF shielding.
RF connector, which provides physical connectivity M320 and the antenna
which is integrated into the notebook computer’s mechanical housing.
Voltage regulation circuitry, which converts power from the host power supply
to the core regulated voltage for the HSDPA wireless components.
System connector, which provides the data, control, power, status and UICC
interface between the host and the wireless network adapter.
All components except for the antenna connector are covered by EMC shields. All
power and base band communication are located in the edge connector of the
board. The fastening holes in the upper corners are connected to ground.
2. Dimensions
The dimension of the board is according to figure below. Note that the figures are
stated without tolerance, see the PCI express mini card electro mechanical
specification for more details.

There is one connector located on the board. The RF connector is of type Hirose
U.FL. The connector is used for UMTS/GSM transmit/receive. The placement is
according to figure above where the board is seen from the primary side.
The edge connector is a straight single 52-pin connector, 26 pins on each side of
the board. The connector is specified in the PCI Express Mini Card specification

3. Installing M320 onto the main board of PC
(1) Insert the mini-PCIe golden finger interface of M320 into the mini-PCIe
connector on the Main Board of PC, then Press down to fix the M320 in the
module slot.
(2) Use a screwdriver to fix the M320 onto the Main Board of PC with two screws.
(3) Insert the connector of antenna cable into the connector of antenna interface
on the M320.
