At the moment I believe Radxa's main reseller is Seeed Studio, I don't think they have a wide distribution network yet.

*Edit: I looked into it further and Radxa only has 2 distributors: Seeed and Allnet https://wiki.radxa.com/Buy

Allnet is located in Germany and China.

Seeed Studio themselves have a wider distribution network, they sell through other distributors like Digi-key. Unfortunately, the Rock Pi X hasn't made it that far yet. Seeed also has a US warehouse for faster shipping but I don't think the Rock Pi X has made it there yet either.

I just ordered a Rock Pi X - 4GB / 128GB along with a number of accessories. I ordered from Allnet China: https://shop.allnetchina.cn/

An important note: If you get one of these boards you need to get the heatsink that is made for it also. Either that or the aluminum case that has the heatsink built into it. 

I choose the Economy Express for shipping- Per their shipping information -

this option is working better because it passes domestic postal services and ships via air cargo into the destination country. There the parcels are handed over to the destination postal services for delivery to the buyer. There are of course also delays but limited

Here's what I ordered and the prices in US dollars:

Seeed had only one size ROCK PI X available that I could find and no accessories. Not even the recommended heatsink was in stock (a must have!).

I'm really looking forward to getting this. Thanks @DJ for showing us this. I've been waiting for something exactly like this to place an onboard computer on my B9 Robot.

This looks pretty cool but what is use case for this. If I still need a EZB to interface with it for servos and sensors isn't it just a smaller weaker computer than my laptop that I use now? I could see if you have some far off robot operating autonomously but I have never used my robots more than 10 feet away from my laptop or without a network anyway. Will it run face recognition much faster than my powerful laptop? Looks like 4G of RAM vs. the 64G I have now. What is it that this will bring to a robot? It seems a funny question to ask because of course a robot needs a computer just wondering if this is a big upgrade for us or if it is an acceptable downgrade for people without a network that just want an on board computer.

@Perry_S, It's small and can be mounted directly on or inside a robot. You can rig it to power on and boot up windows when you power on the robot. ARC can then auto start and it's INT script can set up your robot to run.  After that you can use your mobile app to operate the robot or do whatever your imagination or needs show you.

Can you picture powering up your robot, everything setting up automatically. Then when his face rec sees you he says "HI Perry"!

Hey Perry,

From initial impressions, the Rock Pi X doesn't look like much. For me, personally, it's very exciting because it gives us an x86 computer with a small enough form factor and affordable price that I can stick them inside a robot permanently. Running ARC onboard a robot seems extremely powerful.

It's true that we could do this in the past, but not at this price and availability. It's just within reach now. The Atomic Pi was going to be THE solution for me until I found that it was just a surplus board that would run out of stock eventually. It also was on the low end of requirements with only 2GB RAM and 16GB of eMMC.

The Rock Pi X series with 4GB RAM and 32GB eMMC is a viable solution for the future. It gives us long-term access to onboard computer-based robots. I can now make robots that are completely embedded and I can give robots to other people that won't require them to have to use a laptop or do anything to control the robot, they will be completely self-sufficient.

These SBCs can be remoted into when connected to a local network which removes the need for a monitor, keyboard and mouse connected directly to them. I haven't tested it yet but headless operation should be easy with an HDMI dummy plug. I really like the idea of programming embedded robots in this way.

Thanks for answering guys. I am amazed it is so low priced. I might get one just to play around with it. I ask because I remember when I was really into putting Raspberry PI's into my inmoov. It turned out to be an inconvenience because for every little program changes I had to make either required me to plug in a keyboard and monitor or to VPN into it. So basically I was tweaking parameters and scripts from my laptop. So I ended up with a robot that I usually used my laptop to run with a really weak computer in it. Pulled all that stuff and got an EZB.

Dave, I think the difference between you and I is that you actually have a bot that is so finished Will be cool to see what you guys come up with.

LOL @Perry! Well, maybe not. Our moto in the B9 robot builders club is "A B9 robot is never really finished". Perhaps the operative words in your statement are"so finished". LOL

Have fun!!!!!

Well - if/when jeremie makes the add-on ezb for the rock pi x, it'll be awesome. Just use your laptop to VNC into the robot and have full control via remote desktop. But, the great thing is no wifi between ARC and the controller. That means faster video, higher def video, faster response in auto position, etc... When the WiFi is removed between ARC and the EZB, things become magically more awesome
