Inside Google's Project Tango tablet

Summary:According to Google, the goal of Project Tango is to "give mobile devices a human-scale understanding of space and motion," and the new tablet brings this goal a little closer.

Project Tango is a project run by Google's Advanced Technology and Projects group (ATAP), formerly a division of Motorola. The new tablet joins a smartphone as a device that features sensors to track the 3D motion of the device and build up a 3D model of the environment it is in.

According to Google, the goal of Project Tango is to "give mobile devices a human-scale understanding of space and motion."

A tablet is the latest Project Tango device to be unveiled, and the folks at iFixit got their hands on one to take to pieces.

Note that this tablet is not a commercial device, instead a limited edition development kit "professional developers interested in exploring the future of mobile 3D sensing."

The spec is quite impressive, with the tablet featuring a 7-inch HD 1920 by 1200 (323 pixels-per-inch) touchscreen display, a 2.3 GHz Quad-core NVIDIA Tegra K1 processor (same silicon as found in Nvidia's SHIELD tablet), 4GB of RAM, and 128GB of storage that's expandable thanks to a built-in microSD card slot. On the connectivity front it features wi-fi, Bluetooth LE and 4G LTE.

Here is a listing on the silicon inside the Project Tango tablet.

  • Nvidia TD580D-A1 quad-core Tegra K1 processor
  • SanDisk 4133DF4PG02X 128 GB flash memory
  • Elpida FA232A2MA 2 GB LPDDR3 RAM (two ICs for 4 GB total)
  • Broadcom BCM4752IUB2G integrated multi-constellation GNSS receiver
  • Broadcom BCM43341XKUBG single-chip dual-band combo device supporting 802.11n, Bluetooth 4.0+HS & FM receiver
  • Realtek ACL5642 Hi-Fi audio single chip with voice/sound DSP and CODEC
  • STMicroelectronics STM32L151QD ultra-low-power ARM Cortex-M3 MCU
  • NXP Semiconductors 546A 0108 TXD403
  • ON Semiconductor NCP45560 controlled load switch
  • Nvidia ICE9245B-C2 low-power, multimode RF transceiver
  • Nvidia Icera ICE9045T-A2 LTE modem
  • Texas Instruments TPS659121A PMU
  • Skyworks 77621-11 multimode multiband power amplifier module

But that's not what's special about the Project Tango tablet. What's really special are the eyes of the tablet. Facing the front is a 120-degree camera, while on the back is a 4MP RGB-IR camera and a separate 170-degree motion tracking camera. Google has even put thought into keeping user's fingers away from the cameras, creating a unique design to prevent the cameras being obscured.

Powering all this is a custom dual-cell 7.6V/18Wh Li-ion battery.
