This board was originally built and designed for the high altitude balloon project (). This was the main sensor board and we have affectionately named it the 'every sensor we know' board. It has a humidity, magneto, pressure, temperature, light, and acceleration sensor. In addition, it has an ATmega328 at the heart with connections for a GPS module, radio, and an external temperature sensor.
