Do you know if it is available? On Downloads page there is no separate section for One and I didn't see any schematics.

Quote from registering on the forum : If you have any questions, you can contact with the administrator, Email: admin@xunlong.tv

We all seem to have the same questions : Besides selling the boards, is there anybody responsible for providing informations ( there is NO
support for OPI ONE ) or administering the forum ( the majority of "users" are fake spam entries ).

It migth be easier to learn Chinese and then check back with the busy sellers.

On the brighter side - the forum members are helpful, without them nothing would work at all.
