I dusted off an old Nanode I had with a view to replacing the blown 328P-PU chip.
I’ve seen on this video Updated Wicked Devices Nanode Bootloader with Arduino UNO bootloader - YouTube that you can use a Nanode with the UNO booloader & it seems to work ok.
Does anyone know if the Nanode had it’s own unique bootloader because of its in-built Ethernet capability? There is no option to select Nanode in Arduino IDE - when choosing the board the original instructions were to pick Duemilanove but this was for programming not for flashing the bootloader.
I am happy just now to use it without Ethernet but might want to explore this in future.
