+====THINGS TO DO BEFORE THE CLASS====
 **Software Setup**
 You should do the following things before the class:
+If you are using a Macintosh, install these drivers for the serial board - https://github.com/adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver. I find the CH34x serial chip support on OS X to be spotty at best. Follow the instructions carefully. YOU MUST DELETE ANY OLD VERSIONS OF THE DRIVERS, or kernel panics WILL happen! Linux and Windows machines //should// just work, but if not look for the current CH34x drivers.
 Install Arduino IDE if you don't already have it, and upgrade to something recent if you're below version 1.7 - http://arduino.cc

 and then add #define CLASS_BME280 at the beginning of your program, so that way if you get an Adafruit BME280 board in the future, it will continue to work right...

+Your kit should consist of a number of boards:

 **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

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.
