Well, well, well, I'm on my third version for this board and probably the last. It has basically all the components from the second version, since that board was quite good. So what I've changed. Well, first of all the size. I want to 3D print a case for this projcet so I want the board to be as small as it can get. The width of the board was given by the buck converter. But now I've found another buck converter that is smaller so I could make the board smaller in width. All I wanted is to get this board to be more compact. That's why I've also used a smaller crystal oscillator of 16MHz. Like this, there is a lot more space on thye baord.
