This Project is to produce 3 final Prototypes. All Power Supplies will have USB Charging of Lithium Batteries and a Load Sharing.
Prototype 3: Utilizes a Boost Inverting IC to get +-13V and LDO's to Reduce the voltage between 0 and 12V. Both +- Rail Voltage Current and Power will Be displayed on a Full Color LED Display. Will have a DAC Output, 2 Analog input and 4 DIO Pins. Since the circuit is completely analog the MCU can perform Double duty and Potentially be used as a crude Oscilloscope or Logic Analyzer.
