3. Important Design Considerations

3.1 ON_OFF Signal

To conserve power, the Telit CE910-DUAL does not automatically start up when

power is applied. The baseboard design must supply a means to assert the

ON_OFF signal for the specified time (1 second < hold time < 2 seconds) to

start-up the module. To make module automatically start when power is applied,

tie ON/OFF signal to GND permanently. See Telit Hardware User Guide for

additional details regarding the ON_OFF signal.

3.2 Power Supply Requirements

The module will regularly consume high amounts of current on the Main Power

Supply (VCC), up to 750mA during active transmits and receives. The

baseboard power supply should be designed to support peak currents up to 1

Amp. A 100uF capacitor should be placed near the VCC pin on the module to

ensure ample energy is available, with a low inductance path to the VCC pin.

For example power supply designs, there are multiple references available. See

the NimbeLink Skywire Development Kit schematic for a switching regulator

example, or reference the Telit Hardware User Guide which has an example of

both Linear and Switching regulator designs.

4. Mounting Guidelines

The Skywire embedded cellular modem supports multiple connection methods,

the two primary methods are board to board connectors and soldering directly to

the baseboard.

4.2 Solder to Board connection approach

The module can be soldered directly to a PCB. The PCB should be designed

with two rows of ten, 0.8mm plated thru holes spaced 2mm apart. The two rows

should be 22mm apart. See drawing for recommended footprint. Measurements

are in millimeters.
