Laptop Hardware

The XO-1 laptop is a central focus of One Laptop Per Child. After three years of development, it is in mass production, with hundreds of thousands of units deployed in the field, and thousands more with developers and for testing in schools all over the world.

Main article: Display
  • Liquid-crystal display: 7.5” dual-mode TFT display;
  • Видимая область: 152.4 мм × 114.3 мм;
  • Two "modes" depending on lighting conditions:
(1) Grayscale (B&W) reflective mode: for outdoor use—sunlight-readable; primarily lit from the front by ambient light; high-resolution (200 DPI), 1200(H) × 900(V) grayscale pixels; power consumption 0.1–0.2Watts;
(2) Color, backlight mode: for indoor use; primarily lit from behind by the LED backlight; built in sub-pixel sampling of the displayed color information results in a perceived resolution of approximately 984(H) × 738(V); power consumption 0.2–1.0Watts;
  • The display-controller chip (DCON) with memory that enables the display to remain live with the processor suspended. The DCON also formats data for the display.
  • This Liquid-crystal display is the basis of our extremely low power architecture. The XO is usable while the CPU and much of the motherboard is regularly turned off (and on) so quickly that it's imperceptible to the user. Huge power savings are harvested in this way (e.g. by turning stuff on the motherboard off when it's not being used (if even for a few seconds), while keeping the display on).
Note: web browser images are currently scaled up so that an image of very roughly [800 × 600] fills up the browser window.

Integrated peripherals

Keyboard detail
  • Camera: integrated color video camera; 640 x 480 resolution at 30 FPS; independent (and undefeatable by software) display of microphone and camera recording status; the camera and device driver support disabling AGC and automatic color balancing, to enable its use as a photometric sensor for educational applications;
  • Wireless Networking: Integrated 802.11b/g (2.4GHz) interface; 802.11s (Mesh) networking supported; dual adjustable, rotating antennas support diversity reception; capable of mesh operation when CPU is powered down;
  • Status indicators: Power, battery, and WiFi (2), visible with lid open or closed; Microphone In-Use, and Camera In-Use, visible when lid is open.

External connectors

  • DC power: 6mm (1.65mm center pin) connector; 11 to 18 V input usable, –32 to +40V input tolerated; power draw limited to 18 W; - see power connector dimensions at Battery and power.
  • Headphone output: standard 3.5mm 3-pin switched stereo audio jack;
  • Microphone input: standard 3.5mm 2-pin switched mono microphone jack; selectable 2V DC bias; selectable sensor-input mode (DC or AC coupled);
  • USB: Three Type-A USB 2.0 connectors; Up to 1A power supplied (total);
  • Flash Expansion: SD Card slot.
Connectors

Аккумулятор

Laptop Development Schedule

On April 15, 2006, the first prototypes of the XO, the A1 prototype boards, were first powered on. Development continued with the B1, the first complete prototype laptop, in November of 2006. The B2 laptops were the first to incorporate the CaFE chip, and was produced in small quantities for initial trials in January 2007. In April of 2008 the design was refreshed with a faster processor and more memory/NAND flash. The B3 prototypes were the first test of this design. Slight refinements were incorporated into the B4, manufactured in June 2008, which is very similar to the production version of the laptop. Finally, mass production started in November 2007 with the C2 version.

Serial Adapter

Serialadapter.jpg

In order to conserve parts/space, while the motherboard does provide two serial ports for debugging (one populated in production), it does not provide voltage translators to fully implement the RS-232 protocol. Thus a 3.3V TTL to RS-232 (or USB) Adapter is needed.
