You can use a hot-air solder station or an electric frying pan.
The electric frying pans costs 20-30 dollars, but the hot-air station is better if you make a mistake and need to fix/change something. For hot-air station recommendations, see this thread: The hot-air conundrum I have both, but I use the hot-air station more than the frying pan. (Not because the frying pan is bad, but because the hot-air station is set up and ready to go at any time.)
I use SMD because it’s easier and less work than through-hole components.
It’s only difficult when the components are tiny. The smallest component on the breakout board is 0603, which is is large enough to be fairly easy to do. (I designed it to be easy to assemble.)
