Leonardo No Headers - add voltage regulator

Post by RDeano »

I recently purchased a Leonardo without headers and would like to add on the barrel connector and DC input voltage regulator but have not been able to identify a kit or parts list with instructions for doing so.

Anyone have any idea about where to find something like this?

Also, I'm curious about what options others have used for powering the Leonardo.

Thanks in advance for any suggestions.

If you look down the product page the jack and headers are listed.

Thanks! I looked at the page: http://www.adafruit.com/products/883

and the only component at the page bottom that looked relevant to what I'd like to do is the barrel connector. So you're saying that the only part that needs to be added to a "headerless" Leonardo for external power is the barrel connector? No resistors or other components needed? If that's the case, that's a nice easy fix.

All you need are the mechanicals.

Thanks! So I now understand that the voltage regulator is already onboard the Leonardo. That's great to know.

I assume that by "the mechanicals" (plural) you mean just add a barrel connector (singular).

I'll add the barrel connector and see how it works.

I appreciate the fast responses!

Also the pin header. Things that make mechanical connections.
