It's quite an accomplishment for an individual. You might find the Pine A64 interesting. I got 6 of the 512MB models for $15 each. [1]
I plan on running Kubesolo on them since 1.0 was recently released.[2]

Cool, i wish i had the skills. I'm planning to learn PCB design to build a low power low cost PCB based in the SG2002/LicheeRV Nano design with a MAX17043 battery gauge, gpio buttons and a battery controller like TP4057.
Let me know if you are interested ;-)

That's cool as a project, but I don't really see the point. Everything's hungry for memory these days. DDR3 is a relative bargain. Why not put a socket on there so you can add a cheap 8GiB laptop DIMM?

Very cool!
A few questions:
How was the 696 MHz DDR3 RAM speed determined?
Also, how is the system initialized at startup? Is there boot/startup code, does that exist in a flash chip (or some other ROM or EEPROM or flash type chip) on the system, and can the boot code be inspected/customized/overwritten by the end-user? How does the system boot?
Anyway, looks very cool!
