They are a Chinese hardware manufacturer. The firmware source code appears to be open and on GitHub, but the hardware is fully closed. Accordingly, they are not "Open Source Hardware". They are not even "Source Available" on the hardware side.

one way to put them would be on a list of PRC funded startups, for instance. also I have no idea whether you worked with their hardware before and at which level; I have, and their concept of "open" source HW is very different from what OP is talking about
