    Power Selection Module

    • Power inputs must be between 4.4v and 5.7v
    • Power output is the same voltage as the selected input.
    • Power can be taken off the PSM in different methods, allowing for different subsystems to fail gracefully.
    • This module also holds the Buzzer controller.
    • The Aux power input has a Zener clamping it to 5.6v, this zener is protected from continuous over voltages by a fuse and fet.
