There are many boards of rk3568, please don't mix them up

As far as I know, I saw a lot of rk3568 development boards here.

Some people regard r68s as r5s and change my title:)

R68s, r5s, m68s, h68k series

Let me tell you the general difference: (it's really general, with small mistakes)

4G is generally 10$more expensive than 2G, and the price is 2G

Thank you for sharing. I have this board and am having some trouble finding a good firmware version for it. It seems I have someone's version that doesn't meet my need.

Could you point me to one I could flash in place of this?

The device I have is a Seeed Studio Link Star
