Every MadLab kit includes a professionally-manufactured printed circuit board, quality components, and full assembly instructions.
To build a MadLab kit you will need some basic tools. You'll need a soldering iron with a fine tip, some solder, a pair of wire cutters, and most importantly some safety goggles. You might also find if useful to have a solder sucker. This is indispensible if you make a mistake and need to unsolder a component.
