Convert arduino nano to 3.3v

Other Hardware General Electronics

Hi,

I already converted my uno to 3.3v and it's pretty easy. Despite some people saying it shoudl not work with a clock of 16mhz at 3.3v it works amazingly well.

So now I want to convert arduino nano to 3.3.v Ok, changing the voltage regulator is easy but some tutorials in the internet advise 2 more changes (with jumpers) but other tutorials contradicts this. I think these 2 changes are related to USB interface.

So I ask you: what else should I change in hardware after replacing the voltage regulator to the 3.3v version?

They often do work at least for a while, but are outside of specification.

If you dont mind the prospect of your project stopping working at random, then fine.

It depends on the Nano design and if it is a clone or not.
Here is one I did: Arduino Nano CH340G 3.3 volt conversion - Project Guidance - Arduino Forum . You'll see a schematic there which you should compare with your own Nano before starting.

Wow Arduino Nano CH340G 3.3 volt conversion - Project Guidance - Arduino Forum is really great! I will take a look at it as soon as I get home :wink:
