Okdo or radxa boards

I am new to rockchip embedded boards. What’s the difference between OKDo and Radxa boards (Rock cm 3, 4 se, c+, etc). It’s confusing because they all have the same version names and seemingly same physical layout.

They’re identical. OKdo and Radxa seem to have a partnership which allows OKdo to sell the boards under their own brand.

Ok, cool. Thanks!

I wonder if they have slightly different OS builds on their downloads. Seems to me Radxa is more active on updating. I may be wrong.

Yeah. Though I suggest going with something like Armbian.

Ok, I will have research that a bit. What’s the advantage of Armbian vs the recommended Debian 10 version on downloads?
