I bought the Qotom-Q190G4-S02. Worked good so far, I installed pfsense.
But one day later the msata SSD crashed and the pf sense installation doesn't work anymore.
I used an external USB stick now, reinstalled pfsense - and it seems to work. So it seems that just the msata SSD is defective.
One day before pfsense already reported some errors with the drive.

Any chance to get a working msata 32GB?
I'm sorry to hear that. Could you provide the order number? Our sale will contact you by email.

Hello, I brought it via amazon. I installed pfsense (last version), now it doesn't boot and goes always in uefi shell. Even after bios reset. What can I do? My order: # 404-1310931-6861921

Just bought two of these from the Amazon Store. Installed MSATA and 2 GB RAM in on of them. Turning on the power gives me a green light. And nothing else happens. VGA seems completely dead. How should I proceed?
