items received in the expected date, good overall performance but the Linux OS is a little crappy

Flashed correct image (headless) plugged it into my network and had an ssh session within minutes. Really awesome little boards.

With the current chip shortage, I have been looking for a replacement for or an addition to my Raspberry Pi's. From the description one would think the Khdas would have been a great runner up. It says it supports Linux, speciifically tested with Ubuntu, and has some AI chips which I believe is what is running the AI off of the EMMC memory, There were some other bonuses that seem to make this a good option, you could flah the EMMC to run your Linux direct from there as opposed to the SD Card, it has only 4GB Ram, but such a board really doesn't need a ton of RAM so I was OK with that. You can add an m.2 drive, which I have not tried but read it could be done. Over all the power of this board and it's features which include the 40 pin GPIO makes one think it would make a great replacement for Raspberry, if not a worthy competitor. However, the issues that concern me are the same with many of these engineering boards, very little support, no manual, no good documentation, and nothing to help you support the use of this board. Also, this is supposed to be a High Performance: Amlogic A311D - x4 2.2Ghz Cortex A73, x2 1.8Ghz Cortex A53 12nm SoC however, once I figured out that this could not run Linux, atleast not any standard flavor of linux, and found that it has only been tested by the manufacturer with a flavor compiled just for this board, I found that the video out (via HDMI) was stuck in monochrome orange. So I reimaged the SD card with an earlier compiled Ubuntu version on Khadas's website and that seem to fix the color issue, however, the board is extremely slow. This is definitely not running at 1.8Ghz, or rhwe 2.2Ghz one should be getting. I contacted Khadas via their website with some questions, as well as via their message us on Facebook, and each time even after explaining I had been to the forums and read the documents online, I was continually redirect back to those same resources. So there is no support by the maker for this board. Now, to clear one thing up. I am not saying that this is a POS, and you should avoid it. In fact, what I will say is that if you know your intentions and this board supports those intentions, then for the price, this is an excellent board. However, if your a maker who has a specific project in mine and need some hardware flexibility where you are not locked to 1 specific OS, and only 1 specific precompiled OS with no other options and you (like me) are not able to compile your own OS, then you will wont to consider something else. This board is going to be for the more senior of the makers, coders, and those who's bag of tricks would not fit in a pickup truck. For me, I am not stuck with the question as to whether I return this as it's not as described since it says it supports Ubuntu but it doesn't, it supports only their compiled verion of Ubuntu with no other OS's compiled. Or do I keep it, and use it as a NAS freeing up one of my other Raspberries. Right now, that seems like the logical thing to do, just do to the costs savings as these boards compared to Raspberries are pretty cheap. So that is my take on the Khadas. I am not basing it, nor am I giving it a glowing review. I am simply telling you that you need to know what you goal is with this board and if you feel you can achieve that. If not, then this board is not for you. If you can, then this is a great board for the money, and right now, it's the cheapest option on the market, and its a solid board from my experience thus far. I just wish I understood why it is so slow compared to my Raspberry which is a 1.5Quad Core. The Khadas should be much faster but it definitely doesn't appear to be, and that is likely do to the singular OS, Best to all. I would love to hear about others thoughts on this board. Thanks

Board setup all wrong power and USB are to close i have not been able to get a vim Image to boot from SD and there are no instructions

Tried a generic usb 7" touchscreen and Android did not recognize screen taps. Works better with a 20" monitor and wireless mouse/keyboard. Anyway it met my needs as a platform for usb over wifi (running Ubuntu, not Android). I am impressed.
