I have a small project that uses the 328P chip. It will operated two motor driver boards and an OLED. Will the NANO board do the same so I do not have to build a PCB and so on just using the chip? Seems it would be so much easier. Thank you!
Yes.
For your information, breadboard version of bare-bone 328P:
Yes. Most of the Arduino boards are simple break-out boards for the microcontroller, with a voltage regulator and a serial interface...

Thank you!
If you operate on a battery the arduino boards (with leds and other stuff) will draw more power than a design without the bells and jingles.
There are ways nevertheless to get rid of some of those "power hungry" components and build a low power design from boards such as Arduino Pro Mini. Arduino no longer manufactures those but there are lots of clones available and it’s the same 328P underneath
