C&DH: The Command and Data Handling (C&DH) board is the "brains" of the satellite.  It interfaces with the radio and the GPS board, receives ground commands, maintains the "calendar" of events, and controls all of the other boards.  The C&DH board also has an SD card for saving the science data. During normal operations, C&DH is constantly monitoring battery voltage to make sure there is enough power to finish each step, and can keep the satellite in a low-power mode if needed to charge.
