1.2. Product Overview

The Skywire® Development Kit includes one baseboard, antenna, power supply, SIM

cards, and debug cables. Skywire modems must be purchased separately. The kit

enables you to develop your application directly on the Skywire modem with three

different ways to connect:

● Connect your PC to the Skywire modem UART port via onboard USB-to-UART

converter and send AT commands directly to the modem through PC terminal

applications. You can also connect over USB for access to multiple COM ports.

● The kit is an Arduino shield, so you can plug the kit directly onto an Arduino

microcontroller. Please see Section 4: Common Next Steps for links to example

documentation.

● To connect the kit to a different processor or development kit, a 14-pin header

breaks out the necessary signals for easy connection to any device. The modem

supports I/O levels from 1.65-5.5V, simplifying connection to other systems.

1.3. Block Diagram

*X2 and X3 U.FL connectors not present on all modems.

2. Connect to Kit using a PC

This section covers how to connect your development kit to a PC and provision

the modem with your cellular plan. It also covers how to communicate over the

serial port to the Skywire modem which only requires the use of USB port and

connector marked J14 or USB2 in the diagram below. USB1 (connector J5) is

used for high speed data connections and firmware updates to the modem and is

not used in this section.

2.1. Unpack Kit Contents

2.2. Skywire Placement

To mount your Skywire Cellular modem follow these steps:

1. Gather the following:

a. Skywire Development Kit board

b. Skywire Cellular Modem

c. U.FL extractor tool (Always use a U.FL extractor tool when placing or

removing U.FL cables on the Skywire modem to avoid damaging the U.FL

connectors).

2. Line up your Skywire’s cellular U.FL connector(s) on the side of the board closest

to the antenna connector. Depending on the type of Skywire Modem you have

there may be one, two, or three U.FL connections.

3. To avoid damage to the U.FL connector and maximize connector life, a U.FL

removal tool should be used when attaching/removing the U.FL connector.

Always insert and remove the U.FL connector with a force perpendicular to the

board. If your Skywire is using GPS, attach the GPS antenna to the bottom of the

Skywire connector X3. If you are not using your Skywire’s GPS or if your Skywire

does not support GPS, continue to step 4.

4. Attach the U.FL cable to the top U.FL connector X1 on the Skywire. If you are

using a Skywire with the cellular diversity antenna option attach a second

antenna to connector X2.

5. Carefully seat your Skywire into the board’s Skywire socket (U1). Take care to

ensure that the pins are correctly aligned. Failure to properly align the pins may

damage your Skywire.

connector X1.

A common issue is accidentally inserting the modem with pins

misaligned by one row. Check pin alignment BEFORE applying

power to prevent modem damage.

2.3. Attach Antenna to Baseboard

Antenna screws onto SMA connector with a clockwise rotation

2.4. Short Jumper J6

Ensure header J6 is shorted with 2 pin Jumper. This enables USB to UART

communication between the PC and the modem.

2.5. Attach Jumper Wires (NL-SW-LTE-WM14

only)

To power on the NL-SW-LTE-WM14 modem, you must tie the SW_ON_OFF pin

to GND. Place a jumper wire to connect header J8 Pins 2 and 8 together.

Please see page 3 of the Skywire Development Kit schematic for pin locations:

2.6. Plug in 12V Power Supply to connector J15

2.7. Plug USB cable into connector J14 and PC

2.8. Power On the Modem

Press and hold button S1 to power on the modem. Please see the table below for

the length of time needed to hold down button S1 for your particular modem.
