 +  * First things first- TEST THE VOLTAGE REGULATOR BOARD. Unfortunately,​ these boards are capable of failing short (i.e. the input voltage can end up at the output, which will fry your ESP8266!!). Hook up your power source to the Vin of the regulator board. Using a voltmeter, check the voltage at Vout. It should be about 3.3V, give or take .1 V. If it is more than this, get another board and throw this one away!

   * 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.
