Custom arduino board Hey There Arduino Coders. I am a relatively seasoned C/C++ programmer. However, I'm still new to the Arduino Game. I'm coming here today to ask you guys a direct question that I couldn't find a direct answer for on google... here it goes:

Is it possible,(also practical) to create my own arduino board? after creating a prototype with an arduino uno and various shields?

In other words. Is it possible to shrink the arduino(make a custom arduino), and all of its shields on to one board? It seems rather large to have to lug around all of those shields and such. CHEERS!
I have a page about a breadboard Arduino which is basically an Atmega328P processor (same as in the Uno, inter alia) on a breadboard.





Also a wire-wrapped Arduino.





You can go pretty minimalistic with a ATtiny85 mounted on a button battery like this:

Ah there you might be asking a bit much. There are hundreds, if not thousands, of shields people have designed for it. Certainly you can make up your own board to meet a specific purpose.
