Solder headers

The more traditional method of attaching your GPIO headers, and the one I have always used, is to solder them to the board. As I mentioned earlier, for most of the projects, I will not attach the header blocks in this manner and will just solder directly to the board; however, this is a skill worth learning, and some of the add-on cards or hats we will be using will require us to attach the headers before we can use them.

I include this section more for completeness about setting up a Raspberry Pi Zero, but as you will see in the projects in this book, I will be soldering our components directly to the Pi Zero and not making use of header pins. If you choose to solder the headers to your Pi Zero, then you will be able to follow the projects in the book by soldering to your header pins rather than directly doing so to the Pi.
