khadasEdge2 (Edge2's Active Cooling Kit), Includes Edge Heatsink and 3705 Cooling Fan

The product has turned out to be exactly as described and so tiny! The over the air update of firmware and OS install are quite an impressive experience. The Ubuntu distribution is great out of the box, I have not tried other Linux flavors, expecting there may be device driver items to address, but the out of the box to up and running was quite good.As with any quick-start Linux distribution, there are items to address security wise, such as the default account / password, turning on the Firewall, creating a non-Admin user for your Day to Day work, but for the target audience of a Maker, your up and going without the need for an external PC or Laptop.

I figured out what was wrong with these guys. They REQUIRE a proprietary 12v 24-30W USB-c power supply. It is not available in the United States. Without the proprietary psu you will not be able to use any add ons. I tried using numerous psu and I cannot get any of the components to power let alone the board. I can get the board powered fine but once I add on any component the board cannot power. I have used psu's that have anywhere from 10W to 100W. It is the board itself must have their psu.I went to their documentation and it is empty. The info in there is barely readable and it skims the topic. So if you want to enable a dt overlay or make the camera or screen work there is no info on it.If you go to their site you will see that they do not separate the components. It is impossible to tell what you can use. The site is really poorly laid out. Again it provides no good information on how to use the board. Raspberry pi, udoo, latte panda are all much better. They include the power supply and have complete docs. well udoo was slim.This board is not a good buy. Stick to a device that you know will work.

This is the second board that has issues this one at least lasted a couple months but seems there is some quality issues with them for the cost I’d recommend a cheaper board like the nano.

Board stopped working not sure if it was a heat issue but did spend the extra 25 for this cooler.

This board with its heatsink + fan is powerful and compact. I love the integrated OS loader. After testing this board I sold my RK3588S based boards from firefly and SeeYouToo. Those were great boards too. But this one is better in my opinion.
