   * If you plan on re-using the boards for something else in the future, solder in header pins on the other boards. If you're building this as a fixed-in-place design, you'll want to just solder wires to the boards. Theoretically, the person that designed this de-solders the pins from the ESP8266 board, but that seems foolhardy to me (makes it MUCH more difficult to reprogram...)   * If you plan on re-using the boards for something else in the future, solder in header pins on the other boards.
