Received my BOLT V8 today (US tax day .) Inside the box there is the BOLT SBC in anti-static bag and is well protected by forms on all 4 sides. Added the 4GB DDR4 SODIMM (mine is 2133MHz type.) Try the 20V DC in jack (4.0mm x 2.9mm x 1.0mm center pin), only outer ring (negative) and inner ring (positive) are used by BOLT. Center signal pin (the 1mm one) is not used. This is the standard power supply plug found in some recent laptops. I use this one from eBay (search 183301986663 ), total cost is $11, shipping included. On USB-C based power supply: I tried my 45W PD battery pack (which can supply 20V 2.25A) but BOLT's USB-C won't activate it (it only want to talk to a 60W 20V 3A PD power source, not 45W.) I tried an AC-DC USB-C PD power supply used by recent Macbook Pro (known as Apple 61W, model number A1718) that will work as USB-C based power supply. I tried other AC-DC 45W PD (can do 20V 2.25A) power adapters but they will not work. I.e., 60W PD (20V 3A) is essential.
More notes: I used the HDMI port closest to the corner. My single DDR4 SODIMM is closest to the fan. Fan came up fairly frequently (and is a bit noisy.) Note when first time power the board up, it took more than 1 minute to see some meaningful activities. I think it's BIOS configuration initialization activity. The eMMC is a DF4032. It seems that it's blank. I do not see UEFI shell anywhere. So without any bootable device, BIOS setup screen will always show up. (In BIOS menu, some of the Ryzen BIOS configuration items are foreign to me. I am more familiar with Intel based BIOS config.) When I initially plug in the 20V power, the power consumption is around 20.4V 0.05A (a little bit over 1 W.) When I loaded OS (I tried Ubuntu 16.04 LTS and installed on a key B+E SATA 512GB SSD on key-B slot), the power consumption varies (without stress testing, it can go as high as 20V 1.7A and as low as 20V 0.7A.) After I shutdown the Linux OS, I observed the power consumption as 20V 0.033A (0.66 W.)
I only tried Ubuntu 16.04 LTS. It cannot find the graphics card driver so I am stuck at 800x600 VGA driver mode resolution. The default install also cannot find eMMC as a possible target installation candidate (no driver loaded.) (I also live-upgraded to 18.04 LTS, the graphics driver is also not found. Not only that, without changing the boot flag, the Linux GUI screen won't show up.)
It would be helpful that UDOO puts the drivers in a site for download. It is rather inconvenient/difficult to get the drivers from AMD (need to create developer's account, etc.)
This drivers works but little bit old: https://www.touslesdrivers.com/index.php?v_page=23&v_code=58287&v_langue=en

Thank you for providing all your firsthand information on the new Udoo Volt (I presume V8). What is your guess as to the suitability of this 90 Watt power supply: https://www.ebay.com/itm/173005451394 ?

The tip size is incorrect. This ebay item 113553773925 is a flavor of tip converter (but still not the type for your ebay link.) Use my link: "I use this one from eBay (search 183301986663 ), total cost is $11, shipping included" to find an equivalent one that is shipped from US.
Thanks. This tip converter looks to be the correct adapter for the power supply I suggested: https://www.ebay.com/itm/152851311981. I understand, but the power supply I suggested is rated at 90 Watts, as is this one: https://www.ebay.com/itm/172255258165 . Given the your lack of success with the 45 Watt supply you tired, I'm thinking that 60 Watts is the minimum power the V8 will accept, so 90 Watts may provide a bit of useful headroom. On the other hand, apparently the V8 and power supply are able to communicate their needs and specifications, so perhaps the V8 may reject the 90 Watt supply in favor of a 60 Watt supply as it apparently did with the 45 Watt supply you tired. Thoughts?
Not sure what your plan is on the power supply. Key is the final DC plug is the 4.5 x 3.0mm type (with an optional center pin.) This avoids USB-C PD negotiation altogether. Re: USB-C PD negotiation Over spec is fine. Under spec (e.g., 45W PD, can output up to 15V, etc.) is not.
These diagrams are to show BOLT's internal hardware mappings, after device drivers are loaded successfully. To deal with missing software device driver in Windows, standard Microsoft tool such as Control Panel > Device Manager is still the recommended tool to use.
I used a USB-C debugger to check BOLT's USB-C port's output (as PD souring) capability. CN8 (the USB-C port nearest to Ethernet port) is labeled (per PD protocol transaction) as 5V 3A 15W capable, No other capabilities exist nor it supports QC2, QC3, and other classic USB powering scheme. CN9 is similar with CN8 except that it is only rated/capable for PD Source 5V 1A 5W.
For anyone else looking for the direct link to AMD drivers, the URL has changed slightly resulting in a 404 for the old one. https://www.amd.com/en/support/embe...rocessors/v-series-v1000-radeon-vega-graphics
have you done any speed tests? I would like to know if speed can be reached according to USB 3.1 specification at any port, even if all ports are occupied. A summary of what is shown in the pictures: CN8: USB 2.0 & USB 3.2 Gen 2×1 USB 3.1 Gen 2 (old wording: USB 3.1) / USB-C CN9: USB 2.0 & USB 3.2 Gen 2×1 USB 3.1 Gen 2 (old wording: USB 3.1) / USB-C CN21: USB 2.0 & USB 3.2 Gen 2×1 USB 3.1 Gen 2 (old wording: USB 3.1) / USB-A CN22: USB 2.0 & USB 3.2 Gen 2×1 USB 3.1 Gen 2 (old wording: USB 3.1) / USB-A Arduino: USB 1.1 Key-E: USB 2.0 or 1.1 correct?
