Power Regulator Board
This custom PCB contains two linear +5 volt regulators (LM7805) and one adjustable switching voltage regulator (LM2576HVT-ADJ) set to output +8 volts. The input voltage for all three regulators is +12 volts supplied by a AC/DC power supply (Mean Well S-100F-12). The +8 volt output was used to power the stepper motor and the motor driver board. The two +5 volt outputs were used to power the URF sensor and the servo motor used for coarse alignment. One of the +5 volt outputs could also be used to power the microcontroller.
