Milk-V has much more than the duo. I have a few of their products and they're very cool!

The biggest problem with them is software. Many boards only have buildroot SDKs or niche and outdated. Fedora related images.

Though if you're experienced you can port your own linux distributions to these boards.

But Duo is a device in the form factor of Arduino Nano that can run actual Linux (the 256MB RAM version at least). It's quite a leap.
