• Power and Serial Cables

Before you can do anything with a gumstix motherboard, you'll need a power and serial cable. The details below will help you to build these. You will need:

Power

Power is supplied via a power header on a connected expansion header. The net powered is called V_BATT. This is then regulated down to 3.3V. The photo shows how a power connector is connected. Double check the connections in case the pins on your connector vary to those shown.

Serial

The connections for the serial cable are shown here. The photo shows the backs (solder bucket side) of the two connectors.

• First Boot

Connect the serial cable to the Full Function serial port. To output the serial data from the gumstix to a terminal use the following commands:

> stty -F /dev/ttyS0 115200
> cat /dev/ttyS0

Connect the power cable to one of the gumstix expansion boards.

• Networking

The netwifimicrosd expansion card provides both wireless and wired USB. The card is shown below.

To use a static IP address you'll need to edit the /etc/network/interfaces file.

auto eth0
iface eth0 inet static
address 192.168.1.72
netmask 255.255.255.0
gateway 192.168.1.10

Once the network is up and running, you should be able to ssh into the gumstix. Connectiong via ssh means you can do away with the serial connection.

• Services

• GPS

The GPSStix expansion includes a GPS module.

The GPS Module uses the Standard UART (STUART). This can be accessed via /dev/ttyS2
