Dev boards run KitKat on quad-core Snapdragon 805

Sep 11, 2014 — by Eric Brown 3,694 views

[Updated Sep 12] — Intrinsyc debuted a SODIMM-style COM with up to 3GB RAM and 64GB flash, running Android 4.4 on a quad-core 2.5GHz Snapdragon 805, and a Nano-ITX baseboard.

If you’d like to design with the same high-powered ARM Cortex-A15 silicon found in the latest Android smartphones and tablets, Intrinsyc Technologies has the board combo for you. Like its Mobile Development Platform Tablet (MDP/T) reference design released earlier this year, the $219 Open-Q 8084 System-on-Module (SOM) and $449 Development Kit build on the Qualcomm Snapdragon 805. The Snapdragon 805 combines four Cortex-A15-like Krait 450 cores clocked at 2.5GHz with an Adreno 420 GPU claimed to be 40 percent faster than the previous Adreno 330.

The Open-Q 8084 module has the same Open-Q branding as Intrinsyc’s earlier Snapdragon 800-based, 70 x 70mm Open-Q 8074 computer-on-module. However, instead of using that COM’s Qseven form-factor, the new board adopts the same 82mm width and 314-pin MXM 3.0 edge connector as the SMARC and EDM COM standards, but with a shorter, 35mm height than either of those formats offers. Additionally, the new Intrinsyc COM’s edge connector interface employs a completely custom pinout — so don’t try plugging it into a SMARC or EDM socket!

The Open-Q 8084 module and associated development board target applications including smart glasses, medical imaging systems, videoconferencing, and digital signage, says Intrinsyc. Major capabilities are said to include:


  • 4K capture with H.264 (AVC) format
  • 4K playback with H.264 (AVC) and H.265 (HEVC) formats
  • 4K Ultra HD on-device display concurrent with 4K Ultra HD output to HDTV
  • HD multichannel audio with DTS-HD and Dolby Digital Plus
  • Asynchronous Symmetrical Multi-Processing (aSMP) power sensing and control
  • Broad sensor support

The module is equipped with 3GB of LPDDR3 RAM plus 16GB of eMMC 5.0 flash, expandable to 64GB. The latest 802.11ac WiFi and Bluetooth 4.1 are built-in along with power management circuitry. Everything else flows through the 314-pin MXM 3.0 edge connector, as described below.
