9Tripod X3399 SoM and Development Board are Powered by Rockchip RK3399 Hexa Core Processor

February 17th, 2017 2 comments

9Tripod (九鼎创展) has just launched X3399 system-on-module powered by Rockchip RK3399 hexa-core Cortex A72/A53 processor, and as well as a corresponding development board for people wanted to get started quickly before designing their own baseboard.

X3399 core board preliminary specifications:

  • SoC – Rockchip RK3399 hexa-core big.LITTLE processor with two ARM Cortex A72 cores up to 2.0 GHz, four Cortex A53 cores, and a ARM Mali-T860 MP4 GPU with OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL and DX 11 support
  • System Memory – 2GB LPDDR3 (2x Samsung K4E8E304EE-EGCF)
  • Storage – 8GB eMMC 5.0 flash (Samsung KLM8G1GEND-B031)
  • IOs – 204-pin to be soldered on baseboard
  • PMIC – Rockchip RK808-D
  • Dimensions – 55×55 mm

9Tripod does have a forum in English, but the company provides most of the information in Chinese.  I could not find details about Linux or Android images and source code, except a few mentions of Linux Qt, Ubuntu, and Android OS on a WIP Wiki, and that the bootloader used is xboot open source bootloader managed by 9Tripod community. There are some PDF documents with more details, but I failed to download them even after registration. If somebody could download them, and re-uploaded them somewhere, it would be appreciated.

The company also provides X399BV1 development board with the RK3399 system-on-module soldered on, and the following (preliminary) specifications:

  • Storage – micro SD card
  • Video Output / Display IF – HDMI 2.0, 2x MIPI DSI connector, 1x MIPI DSI dual connector
  • Audio – Via HDMI, optical S/PDIF 3.5mm headphone jack, left and right speaker headers, 2x on-board microphones
  • Camera – MIPI CSI connector, CIF camera connector
  • Connectivity – Gigabit Ethernet, Ampak AP6354 wireless module with 802.11 n/g/n/ac WiFi 2x2MIMO, and Bluetooth 4.1 LE, micro SIM slot
  • USB – 1x USB type C port, 1x USB 3.0 port, 2x USB 2.0 host ports.
  • Serial- DB9 RS-232 port, TTL UART connector
  • Misc – Buttons, RTC + battery slot

The specifications above have been derived from the board’s photos only. I could not figure the two “connectors” on the bottom of the board are for. An IO header appears to be completely missing from the board, a big omission for a “development” board.

9Tripod X3399 CoreBoard can be purchased for 599 CNY on Taobao (~$87) , while the developer board goes for 999 CNY ($145). If you don’t need a system-on-module for your own project, and/or can’t read Chinese, you’ll probably be much better served by Firefly-RK3399 development board instead.

Mediatek MT8173 Powered Emdoor 2-in-1 Laptops Run Android or Remix OS

December 23rd, 2016 1 comment

Acer Chromebook R13 is the most powered ARM Chromebook so far thanks to its Mediatek MT8173 quad core processor combining two ARM Cortex A72 cores and Cortex A53 cores, as well as a PowerVR GX6250 GPU, 4GB RAM and a 13.3″ touchscreen display. But unless you live in the US or other markets where Chromebooks are sold, it’s pretty hard to buy, and that model is relatively expensive as it sells for close to $550 on Amazon. Emdoor, a Chinese design house, has made 2-in-1 hybrid laptops based on the processor with a 11.6″ or 13.3″ touchscreen display, 1 to 2GB RAM, and 16 to 64GB storage, which – once launched – should be easier to buy, and cost less.

mediatek-mt8173-laptopBoth EM-T8513 and EM-T8516 models share most of the same specifications, except for the display:

  • SoC – Mediatek MT8173 quad core processor with 2x Cortex A72 cores @ up to 2.0 GHz, 2x Cortex A53 cores, and a PowerVR GX6250 GPU
  • System Memory – 1 or 2 GB DDR3 RAM
  • Storage – 16GB, 32GB, 64, or 128 GB eMMC flash + micro SD slot
  • Display
    • EM-T8516 – 11.6” IPS LCD screen with 1366 x 768 resolution,  10-points capacitive touchscreen
    • EM-T8513 – 13.3” IPS LCD screen with 1920 x 1200 or 1366 x 768 resolution,  10-points capacitive touchscreen
  • Video Output – mini HDMI port
  • Audio – mini HDMI port, 3.5mm combo audio jack,
  • Connectivity – 802.11 b/g/n/ac WiFi, Bluetooth and GPS via MT6630 chipset
  • USB – 1x USB 3.0 port, 1x USB 2.0 port
  • Camera – 2MP front-facing camera
  • Sensor – G-sensor
  • User Input – QWERTY keyboard and touchpad
  • Battery – 10,000 mAh; good for a typical 6 to 7 hours on EM-T8516 model
  • Power Supply – 5V/2.5A
  • Dimensions & Weight
    • EM-T8516 – 297.5 x 202 x 17.5mm – 1340 grams
    • EM-T8513 – 330 x 227.7 x 18.9mm – 1480 grams

The laptops run Android 6.0 by default, but Jide’s Remix OS can also be installed instead.


If you are interested in Linux, you could try to adapt the instructions to install ArchLinux ARM on Acer Chromebook R13 to Emdoor laptops. The instructions are relying on Chrome OS, but you’d have to handle it from Android instead, so there will be differences.

Pricing and availability information have not been disclosed yet. You may be able to find more details via Emdoor’s products page (N.B: It takes about 10 to 15 minutes to load a page for me).

  • Dimension & Weight – TBD

rockchip-rk3399-android-tv-boxThe box will run Android 6.0, and currently gets about 72,500 points in Antutu 6.x with 16,519 points for 3D graphics, 25,805 points for UX, 25,905 points for CPU, and 4254 points for RAM tests. There’s hope a good Linux support on Rockchip RK3399, as Google and Rockchip are working on RK3399 Chromebooks, actively committing code to mainline kernel, and Firefly has ported Ubuntu 16.04 to their RK3399 development board with 3D graphics acceleration, and hardware video decoding is coming.

rk3399-sataPrice has now been announced yet, but for reference, Firefly-RK3399 development board with 4GB RAM and 32GB storage is now offered with all accessories for $199 on Kickstarter, and Remix IO+ TV Box also sells with 4GB/32GB configuration sells for $139 shipped, so I’d expect Vorke Z3 to sell for about the same price.

The two new processor still feature MediaTek tri-cluster deca-core architecture with two ARM Cortex A72 cores, four ARM Cortex A53 core, and 4 more low power Cortex A53 cores, but Helio X23  Cortex A72 cores’ max CPU frequency increased from 2.1 GHz to 2.3 GHz, and Helio  X27 got a small boost to 2.6 GHz for the Cortex A72 cores (vs 2.5 GHz) and 1.6 GHz for the low power Cortex A53 cluster, as well as a higher frequency ARM Mali-T880 MP4 GPU at 875 MHz instead of 850 MHz for Helio X25.

MediaTek Helio X23 and X27 also support dual camera photography with the upgraded MediaTek Imagiq image signal-processing solution integrating color and mono cameras and depth-of-field applications into a single ISP.

MiraVision EnergySmart Screen technology modifies the display parameters based on the on-screen content and ambient light in order to deliver up to 25% reduction in display power consumption. The processors also integrate an Envelope Tracking Module dynamically adjusting the output voltage based on signal strength from the power amplifier for an average of 15% reduction in power consumption during peak output.

The company did not give any specific availability for smartphones powered by MediaTek Helio X23 and X27, except it will be available “soon”.  You’ll find a few more details on Mediatek Helio X20 series product page.
