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.
