Yes, you're nit the first telling me this. At first i wanted to make full custom pcb with smd components. But it cost me too much to make just one and some components were difficult to find, so i opted to make more like a shield so is more easy to find the componets and piu easier to solder than SMD for those who have never done it before. This is the same.The last one is also valid for the reason why it was written in Arduino and not in C, that at least even those who are not so familiar with it can modify it
