learning using solar technology; and
• To upgrade our educator’s skills in the use
of ICT for education.
The Project aims to Provide:
•
50 laptop units to the school at Gibitngil, Medellin;
• Solar Technology for the Power Requirements;
• ICT Trainors Training to Administrators and
Educators on the Island;
• Software for Classroom Applications and Lesson
Planning;
• Enhancement Sessions for the local Parent-Teacher
Association to ensure Support for the Project
• Upgrading of our educator’s skills in the use of ICT
for education.

What is the XO Laptop?
What is the XO Laptop?
Hardware:
• CPU: 433 MHz AMD Geode LX-700 at 0.8
watts, with integrated graphics
controller;
• 1200×900 7.5 inch (19 cm) diagonal LCD
(200 dpi) that uses 0.1 to 1.0 W
depending on mode. The two modes are:
• Reflective (backlight off)
monochrome mode for low-power use
in sunlight. This mode provides very
sharp images for high-quality text.
• Backlit color mode, with an
alternance of red, green and blue
pixels. See below for details.
What is the XO Laptop?
Hardware:
• 256 MB of Dual (DDR266) 133 MHz DRAM (in 2006
the specification called for 128 MB of RAM);

• Internal SD card slot;
• Wireless networking using an “Extended Range”
802.11b/g and 802.11s (mesh) Marvell 8388
wireless chip, chosen due to its ability to
autonomously forward packets in the mesh even if
the CPU is powered off. When connected in a
