I'm using a NanoPi R2S without any problems so far.
Now I would like to use another one at my parents home and to connect them via wireguard. But the R2S is hard to get for little money, since it is replaced by the R2C
As I understood the only difference is that a MotorComm YT8521S Gigabit Ethernet transceiver is used (replacing the Realtek RTL8211E from the R2S)
So I'm wondering if its possible to get the R2C working with Openwrt, by just replacing the the lan driver module.
