Quantum Mini Linux Development Kit - anyone have one?

I’m not seeing a lot of detailed information on the Quantum Mini Linux Development Kit. There was supposed to be schematics and I don’t see those either. No indication of support past the first batch ten months ago. Is this an orphan?

I just recieved two of these, and can’t get either set up. I’m not sure if it’s the linux build, an overheating issue, or bad wifi hardware on the SoC, but my serial connection locks up when I try configuring wifi, and only re-etching the micro-SD will get things running.
