Nano vs. Uno

Does the Nano (from Gravitech) come with the bootloader already installed? I have a serial comm application currently running on an Uno; I’d like to replace the hardware with a Nano. Will Uno code run on a Nano? And finally, will the default Arduino IDE work with a Nano?

Thanks!

Look in the boards menu in the IDE.

I would hope so.

Will Uno code run on a Nano?

Yes, it uses the same processor. You'll get problems if you used a different firmware for the ATmega16U2 of the UNO (the USB2serial on-board adapter).

And finally, will the default Arduino IDE work with a Nano?

Yes.
