Specs seem interesting. I took one apart, one memory slot ddr4 4GB, one NVME slot with wifi, one empty NVME slot, emmc on board. Processor is I believe i3-6100u. Seems to default to emmc for booting. There is a small fan, not very loud. Not very useful without being able to bypass the password, unfortunately. I dumped the bios but do not know enough to remove the password.

Here's a new/opened box for $4 + $8.13.
They also have their eBay store, but shipping is more expensive there.

Can you share the dump? I can take a stab at it.

Crazy how much stuff has embedded computers in them now. Nice find! Showing me 20% off for $8 + shipping.

If there was a way to somehow damage/disable the emmc and boot it from the nvme or usb and load pfsense/opnsense/etc onto here to utilize both ethernet ports, this would be the most slick and covert looking router ever! Would be worth too as people would easily pay $50/ea for routers like this that were ready to go. Only drawback I see is that the power supply isn't provided.

Specs show 10/100 ethernet ports, so no good as router, and one is poe passthrough to a phone or camera. I wonder if that second port even has a real ethernet controller or if it is only for proprietary communication with ther device.

Strange to see 10/100 with usb3 and nvme--specs have to be wrong. Both ports seem like they would be real ethernet ports just defined by the software for the purposes labelled. Of course, one won't know until this is hacked and documented. Still a really neat embedded device.

Here some pictures of the internals, Haven't gotten to the other side, the power socket seems to be attached to the casing.

Got some kind of media board with Analog Devices ADV7604 and a Sigma PL330B chip made by avermedia. This seems to be a H264 encoder, so maybe it is a HDMI in. Wondering what the HDMI out specs are, somewhere I read 1080p.
