The NucBox will be one of the smallest 4K-cable mini PCs you can find when it hopefully launches later this year. Specs-wise, it's looking to be an upgrade from the Chuwi Larkbox in terms of CPU performance, WLAN, and RAM.

Hummm... HDMI1.4 ?
Obviously manufacturer claims 4K@60 and HDR in their marketing, andGLK/GLK-R DOES run HDR passthrough to hdmi2.0+ TV with LE9alpha + KODI19alpha (search for LE GLK HDR).
So would be fine to verify the 1.4 for hdmi in your news ;)
There is no second M.2 in the Larkbox... This is a misunderstanding of the editor. in both the larkbox and the nucbox there is only one slot which is used by the m.2 ssd which is ordered with the device.
