I never heard of a kangaroo pc, so that's not a good start.

Here's a good list of officially supported SBCs: https://synthiam.com/Support/Hardware/Hardware-Overview

And here's a list of things to consider when selecting the SBC: https://synthiam.com/Support/Get-Started/how-to-make-a-robot/computer-configuration

And finally, here's how you go about setting it up for performance and such: https://synthiam.com/Support/Tips-to-Make-a-Robot/Overview

I mostly use the Rock Pi/x because it seems the fastest and easiest to get going and doesn't require much effort when installing. The others seem to require additional drivers and such. You'll find everything you need on that first link for drivers, though.

Oh, here's a direct link to the Rock PI/x that i use on most of my robots: https://synthiam.com/Support/Hardware/Rock-Pi-X

Thanks. I will look into. I thought ARC ran on anything that supports Windows 10.

You think correctly that ARC runs on anything that supports Windows 10. However, when you're dealing with SBC's, there are performance considerations. CPUs in portable-style computers are not the same as what is in your laptop - therefore, the CPU will be limited in performance. So, we have documented and verified SBCs that work well with ARC.

Oh, one more thing - if you're considering a 5+ year-old SBC, remember what performance you'll expect from it. Whatever SBC you choose, be sure to follow the performance tips in the support section from my link above.

I can provide some feedback on the Kangaroo as that actually what I'm using right now.

It runs ARC no issues, the Kangaroo does have the Action switch with their built in VNC, but I use tight VNC for access using built in windows Hotspot so its really not a feature that gives it an advantage over anything else.  I will also say the built in battery is not great and dies pretty easily due to poor thermal design. I have run mine using another battery as I have not managed to source a replacement.

Like DJ said its old, I don't think you would find one for sale but if you stumbled upon one they do work, and I can help with drivers if needed.

I was actually looking for alternatives myself, but sourcing a supply seems to be an issue. DJ, I'm not sure if you're allowed too, but any chance you could provide some links to sources for the Pi X? The vendors though the manufacturers page seem to be out of stock.

I had priced one recently, and I was looking at just over $200 CAD from the only source I could find with them. After seeing that price I've been looking at NUC's.

That’s good information about the kangaroo. Thanks for sharing your experience.

The rock pi must be in high demand - plus with the chip shortage that doesn’t seem to end. We list the manufacture page for products, and we could list any other pages if we were given them. Your best bet is to Google around and see if you can find one. I got my last rock pi from Newegg but it took a few weeks.

If you do find somewhere with stock, let us know. I’m sure there are users here who’d like to know as well

Aliexpress has them in stock, if you don't mind waiting for shipment from China? They are much more expensive now though! I believe the 4gb/128gb is around $174.00 - $209.00. Too much for this guy!
