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...)

 **Power considerations**
-The kit does not come with a power source. The regulator board requires at least 4.5V (and at most 15V!) to adequately supply 3.3V to the ESP8266 and BME280 boards. A 9V battery or 6V AA case should work. You should be able to power via USB with the serial board as well- just run wires from 3.3v & ground to the appropriate ESP8266 pins.
