The Vizio VTAB1008 is almost identical to the XO-3, from a software point of view. It uses the Marvell Armada 610 and provides 512MB of memory and 4GB of eMMC storage.

Display

The display size is 8" diagonal w. 4:3 aspect ratio. The resolution is 1024x768.

Connectivity

The VTAB has 802.11b/g WiFi and Bluetooth, using a single antenna.

Location/Movement

The VTAB has both full GPS and an accelerometer.

Ports

  • One USB OTG
  • One mini HDMI output
  • One microSD card, externally accessible (pry out the tab on the bottom edge near the USB/HDMI. ports)

Power

The VTAB has a 22Wh Li-Ion polymer battery.

Breakdown

Still in progress...

The tablet consists of a main PCB, two auxiliary PCBs, and the display sandwich.

Height

The tablet thickness is roughly 12.8mm in the middle. The height stackup is:

Height Stackup
Cover Glass: 1.9mm
Air Gap: 0.8mm
Display: 3.7mm
Swell gap: 0.4mm Main PCB: 4.8mm
Battery: 4.7mm
Back cover: 1.3mm

The touchscreen is a multitouch projected capacitance screen, built with two layers of ITO on the same glass, with a insulating material between the two layers when they cross (known as single glass). The insulating material can be seen as a grid of dots when held at the right angle in sunlight.

The air gap is created by a rim of black foam, 0.8mm in height, placed right outside the active area of the display (mostly on the bezel).

The back cover has a cheap cast metal heat spreader, bonded to the outer plastic shell.

Weight

The tablet weight is roughly 580 grams. This breaks down as:

Weight
Cover Glass/Bezel: 147g
Display: 179g
Main PCB: 45g
Battery: 116g
Back cover and side PCBs: 94g
Total: 581g
