Board Overview
You can use the Single-Board Computer with various open-source projects, but you can do much more.
The Single-Board Computer features a fully functional operating system (OS) that can simultaneously
run multiple processes, giving you a much more robust and versatile experience than a dedicated
microprocessor board.
The Single-Board Computer provides several ports so you can quickly and easily set up a monitor,
keyboard, and mouse to create a complete computing solution.
The HDMI port lets you connect to any HDTV or monitor with an HDMI port.
The USB A port lets you connect USB peripherals. For example, you can use a USB hub to connect a
keyboard, mouse, and other USB devices. The Micro USB port provides additional connectivity.
The MicroSD slot provides an easy way to add additional memory (up to 32 GB).
Note: Your Single-Board Computer is shipped in protective anti-static packaging. The board must not be
subjected to high electrostatic potentials. A grounding strap or similar protective device should be used
when handling the board.

Single-Board Computer Setup
Make USB and HDMI connections before connecting power to the Single-Board Computer. If the board
does not recognize your keyboard or mouse, unplug the device and plug it back in.
Note: To ensure that your Single-Board Computer boots properly, use a short, heavy-gauge USB cable
and a power supply that delivers at least 2 A.
Required Hardware Optional Hardware
•Monitor •MicroSD card for additional memory storage
•HDMI cable
•USB hub
•Keyboard/Mouse
•DC power (Micro USB)

Adjusting Screen Settings
In some cases, the Ubuntu desktop may extend beyond the visible area of your monitor.
To adjust the size of your desktop:
1. Open LX Terminal.
2. At the command prompt, type: sudo setwindow 95 1 0 0
3. Press Enter.
Note: The “95”parameter sets the percentage of screen size, and the “1”activates auto-center; the
remaining values are inactive for auto-center, but are still necessary for the command.12
