Saw some advertisements for the Vilo router (https://www.viloliving.com/), it's super cheap ($28 for single, $70 for 3) and decent enough specs (16MB Flash, 128MB RAM).
Wondering if anyone's tried it and knows about underlying performance/hardware/etc.
According to the interior photos it uses an RTL8197FS for 802.11bgn, and an RTL8812FP for 802.11ac, next to an RTL8367RB for the ethernet switch. A quick search suggests these are Lexra based platforms, meaning no official support from OpenWrt.
A pity, because at that price point it's a really affordable and well equipped mesh solution.
It's not just about drivers. If you search for "Lexra" on the forums you'll see that there's much, much more in the way of supporting it than just drivers.
