I bought a cheap mini-PC board at a street market. The seller said, without confidence, that he was told it’s an “Intel Nano”. But he had a stack of different boards so it’s dodgy info for sure. When I do an image search for “Intel Nano”, nothing quite matches.

I would normally run it and probe for the hardware, but I don’t know how to power it. It looks like there are two pins in a green box that probably need DC power.. likely 12v but I would rather not guess.

Any help identifying this thing would be appreciated!

The “1820” possibly corresponds to “G1820 Celeron”, but that’s a far cry from identifying the model of mini PC.

Oh wow spitting image of the that top photo, yeah I think you've got it.

Edit: It says it's a Kontron product, but I cannot find it in their product page

    Yeah indeed that is the next problem. Some docs would be nice but what I need most is the polarity and voltage. From there I can tinker.

    Found this on another model:

    There is one 2-pin power connector on the top side supporting an input DC voltage range of 24 V DC ±20 %, see Figure 4 (pos. 1). The mating connector required to connect the power connector to a DC main power source is supplied with the BL i.MX6 ULL. For information on how to connect the supplied mating connector to the input power connector, refer to Chapter 6.2.1: Wiring the DC Mating Power Connector. For the pin assignment of the input power connector, refer to Chapter 3.2.1: Power Connector.

    Maybe I’ll start at 12 then try 24v.

    I never really understand what the problem is with undervolting a device, I've heard people worried about brownouts, but... that just means the electronics defaults to the "false / 0" branches in its startup circuity (by my limited understanding)
