ATmega328 with Arduino Uno Optiboot Bootloader

To utilize was very easy, and would utilize for simple project needing breadboard. Very few components to make functional.

Very good to shrink a project down, in space and cost... you can program it using an Arduino Uno and then put it on a board with some components to not have to use a full arduino each time.

once you've figured out what your project is going to do, one of these, a circuit-board and a bit of solder go a long way to building the perfect little MCU with only the bare minimum parts!

Looking forward to using it in my projects

As good as it gets. Chips come with the bootloader installed and the pins are identified. Perfect to test a cirtuit on a breadboard or replace the original chip on the Uno.
