ROCK64 is a Rockchip RK3328 Development Board with Up to 4GB RAM, 4K HDR, Gigabit Ethernet, and USB 3.0

Rockchip RK3328 Android TV boxes such as A5X Plus or A95X R2 have been on the market for a couple of months, but since the processor is rather inexpensive, yet supports 4K UHD video output, Gigabit Ethernet and USB 3.0 interfaces, Pine64 has decided to create a new development board called ROCK64 with a form factor similar to Raspberry Pi 3 board.

The board will support various operating system including Android 7.1, Debian, Yocto Linux, and more. Some of the source code and software development tools are already available in github.

The board will be launched on the first of July, but price has not been announced yet due to the recent DRAM price hike. For reference, RK3328 TV boxes with 1GB RAM now sell for around $35 and the ones with 2GB RAM for around $45. Those prices include shipping and all accessories, and considering Pine64’s usually aggressive pricing, ROCK64 board may be sold for around $25 (1GB RAM), $35 (2GB RAM) and $45 to 50 (4GB RAM) excluding shipping. You’ll find a few more details, including PDF schematics and pinout diagrams, in the product page.

Update: I’ve just received my board, and updated the pictures above. I also came with a FORESEE eMMC module (see first picture), and a 5V/3A power supply.
