Kobol Helios64 RK3399K SBC & 5-Bay NAS Pre-Orders to Start Next Week

We covered Rockchip RK3399K processor a few months ago, as a version of RK3399 processor qualified to run at 2.0 GHz, or supporting a wider-temperature range (-20 to +85°C) at 1.8 GHz.

We found out about the new processor, as Kobol was working on a Helios64 SBC designed for NAS that featured RK3399K SoC. At the time, we just had a drawing of the board and some specifications, but now the company has announced pre-orders for the board and a complete 5-bay NAS kit will start next week and the actual shipping start in March.

Helios64 HeatsinkThe board will ships with a large heatsink as shown above. There’s no mention of OS support in the currently empty Wiki, but we should expect Debian and Armbian support.

Kobol Helios64 5-Bay NAS Enclosure

Kobol’s first product, Helios4 NAS SBC, would optionally ship with an acrylic enclosure which kept cost low, but it was not necessarily the most eye-pleasing design.
