Hello there. I'm on my way to buy some components to my new project and I'm wondering if you could run a small display ( around 2.8" ) and a Raspberry Pi out of a battery? In that case what display and what battery ? I rather have something small cause all this is going in a compact place. I may also have to press in a little Arduino chip thingy. One of them small black things you have on your Arduino.
Thank you for your help in advanced,
