...The design files include the Fritzing CAD files, the etchable PDF PCB layout files, the Gerber files, parts listings, software listings (embedded software listings and Website scripts), and schematics of the circuit boards. There are two circuit boards which are the main controller board and the Timer/Regulator board. The Main controller board performs all the processing of the system. The timer/regulator board converts the 12vdc input voltage to the 3.3v and 5v DC voltages used by the main controller board. The timer/regulator board communicates with the main board via a serial communication cable. The timer/regulator board can be commanded by the main board to power the system down for a precise interval in order to conserve battery power. ...
