The PowerG Arduino Dual Power Supply

The PowerG gives you the ability to control power like the expensive bench top power supplies. It provides two outputs: 5V-12V and 1V-3.3V. You have a choice of current outputs. Use the PowerG connected directly to your laptop and provide a total of 300mAs for both supplies. Or use the
optional 5V external power and provide up to 1.2A for each supply individually.

Get Up To 12 Volts From Your Laptop

The PowerG has two separate Switching Power Supplies. The Power Supply A is a boost regulator which converts the +5V input into +5.5V to +12V output. The Power Supply B is a buck regulator that converts the +5V input into +1V to +3.3V output.

Power Output Options

Using the Laptop to Power the PowerG

• PSA: +5.5V to +12V up to 160mA
• PSB: +1V to +3.3V @ up to 600mA

Using the External +5V @ 4A Barrel Connector to Power the PowerG

• PSA: +5.5V to +12V up to 1.2A
• PSB: +1V to +3.3V @ up to 1.2A

Power Options

The PowerG provides two separate power supplies directly from your laptop. You can power your Arduino, power your sensor from a separate power source, and upload a sketch from the Arduino IDE directly to the bootloader all while using the PowerG.

Display Voltage and Current

You can also get a graph of the voltage and current from both power supply outputs. Each power supply can be turned on or off individually. A single Micro B USB cable is all that is needed to
connect between the PowerG and the PC

Built in USB to Serial Adapter

The PowerG also has a built in USB to Serial Adapter. You can connect up your Arduino and use the IDE to load in a sketch.
