Help creating a PCB

Hello all!,

I am new in electronic and I don’t know how I can design a PCB for an Arduino Uno R3,
a CC 3000 Shield and (https://www.adafruit.com/product/1491) and
a DHT11 (http://www.adafruit.com/product/386).

Best Regards!

Do you want to make a pcb or (as seems more probable) make a drawing of the connections of the 3 parts mentioned connected together? In the later case Fritzing can do that for you. The Uno is in core parts, and I expect the other two may be in the adafruit parts repository (they don’t appear to be in core with a quick search).

I have all of the Adafruit products in my parts bin and both these items are in there,

You can download from here https://github.com/adafruit/Fritzing-Library

Then open the fzbz file with Fritzing.
