OLPC XO-3 Sugar Linux Tablet

The One Laptop Per Child (OLPC) foundation has unveiled the OLPC XO-3 Tablet at CES 2012. This Tablet features a 8″ 1024×768 capacitive LCD touch screen running a version of Sugar Linux for Touchscreen. This must be the only tablet ot running Android at CES 2012… This current sample only have a front camera, but the final device will have both a front and rear camera. They also have an optional solar panel cover (4W panel), that can be used to charge the tablet (2W), so in ideal conditions if you charge it for 2 hours, the tablet can be used for 4 hours. Alternatively, you can also charge it for the hand cracker. A Pixel Qi tablet (not shown in the video below) is also available for extra costs (I’ve heard 100 USD extra) for better readability. OLCP did not specify availability. The way OLPC works is that they […]

OLPC XO 1.75 Hardware, Firmware and Software

OLPC demo’ed their 3rd generation laptop – OLCP XO 1.75 – based on Marvell Armada 610 at CES 2011. The good thing about this platform is that they opened most of it including the hardware, the software and for the first time the firmware. However, I found out it’s not so easy to find the hardware / software development information and source on the OLPC site, so I’ve decided to make a summary and provide links to the hardware, firmware and software for OLPC XO 1.75. OLPC XO 1.75 Hardware The XO-1.75 is powered by Marvell Armada 610 CPU (88AP610) with an ARM core clocked at 1Ghz. It has 1GB DDR3 SDRAM, 4GiB NAND Flash, a TFT display, an SD Card slot, Wi-Fi, a few USB ports and a camera. I believe the touchscreen is not part of the current hardware, but the block diagram below should be close to […]
