The [[BoM|Bill of Materials]] outlines the components needed to build a functional unit. For lab testing purposes the TI Launchpad can be connected directly to a laptop and not powered by the battery.

The "Quick Start Guide":http://www.ti.com/lit/ml/swru312b/swru312b.pdf for the Air Boosterpack outlines the instructions to connect a MSP430 based Launchpad evaluation unit and the boosterpack. These instructions will also help the user bring the unit up to a point where it is running the example software used for testing. Please note that the testing procedure in the guide requires two sets of launchpads and boosterpacks, but this procedure uses one set with a "Ground Sphere Ground Station":https://opendesignengine.net/projects/groundsphere/wiki.

# Set the channel to *915.05 MHz, 7 dBm Max* since that is the frequency that Ground Sphere is designed for.

# Set the *RF Power* level. Your options for the 915 MHz channel will be -60 dBm to 7 dBm. You can set this to the desired level depending on the operational conditions you are simulating and testing Ground Sphere with.
