Title: programing the Nano
Post by: Negative-Bias on July 25, 2015, 08:40:01 am

Hello, I have a arduino uno, and I want to program a arduino nano, I'm not sure what I need to do this, can I use the uno to put the code on a nano, or do I need something else, I come from the pic chip era where I have a programmer , which I suppose is of no use to the arduino system
Any help would be greatly appreciated  and thank you in advance for you knowledge.

You don't need to use the Arduino Uno. Just select tell the Arduino IDE that you are using the Nano (in the Tools menu).

Both the Uno and the Nano have an Atmega328p; the difference as far as the IDE is concerned is the bootloader.  The Uno has Optiboot which is 512 bytes and runs at 115.2kbps.
Some Nanos may be flashed with Optiboot, in which case you just leave the board selection as Uno, even when it is actually the Nano plugged in.
