| - | 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. | + | The kit does not come with a power source.
