We'll add a set of header sockets to Matrix Portal in order to easily plug in the servo motor. A 90º header makes for a nice, compact-yet-accessible setup.
Solder Headers
There are eleven GPIO pins exposed on the Matrix Portal's header row. Trim a section of socket headers to fit as shown.
Place the header and solder it in place.
You could also use right angle header pins here instead of sockets, its just a matter of personal preference.
Wear appropriate protective eyewear and be careful cutting header apart as pieces often fly which could hurt someone.
