XO142

The XO-1.42, commonly referred to as the XO-142, is an educational laptop designed by the One Laptop per Child (OLPC) project, a nonprofit initiative aimed at providing children in developing countries with accessible, durable, and affordable computing tools. Released in 2007, the XO-142 was a successor to the original XO-1 laptop, incorporating several improvements in performance, connectivity, and user interface.

The device features a 7-inch LCD screen with a resolution of 1024x768 pixels, a 600 MHz AMD Geode LX700 processor, and 256 MB of RAM, expandable to 512 MB. Storage is provided by a 1 GB flash memory, which can be upgraded to 4 GB via a microSD card slot. The XO-142 also includes a built-in Wi-Fi adapter for mesh networking, allowing multiple laptops to connect without a central infrastructure, a key feature of the OLPC initiative.

One of the most distinctive aspects of the XO-142 is its rugged design, featuring a reinforced chassis and a durable screen to withstand rough handling, dust, and moisture. The laptop operates on a low-power 700 mAh battery, providing up to 1.5 hours of usage, though it can be charged via USB or AC power. The device runs Sugar, an open-source operating system designed specifically for collaborative learning environments, featuring activities tailored for educational purposes.

The XO-142 was produced in limited quantities and primarily distributed through government and nonprofit partnerships. While it was more advanced than its predecessor, it faced challenges in production costs and scalability, leading to the eventual discontinuation of the OLPC project's hardware development in favor of software and community-focused initiatives. Despite its limited production run, the XO-142 remains a notable example of educational technology aimed at bridging the digital divide.
