For sensors and circuits that need to run on less than 5V, this adapter is an easy solution to integrate it with your Phidgets system. The PSU2001 plugs into a VINT port and steps down the USB voltage as low as 1.5V DC. There's a trim pot on the board to adjust the power source to the desired level, and the source can be turned on and off by toggling the state of the digital output of the VINT port it's connected to.


This device can be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

Product Board
Image Part Number Price Number of VINT Ports Controlled By
HUB0000_0 $30.00 6 USB (Mini-USB)
HUB5000_0 $60.00 6 Local Network (Ethernet or Wi-Fi)
SBC3003_0 $120.00 6

Phidget Cables

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

Part 1: Setup

Welcome to the PSU2001 user guide! In order to get started, make sure you have the following hardware on hand:

Next, you will need to connect the pieces:

  1. Connect the PSU2001 to the VINT Hub using the Phidget cable.
  2. Connect the VINT Hub to your computer with a USB cable.
  3. Turn on the digital output and measure the PSU2001's output using the multimeter or voltage input
  4. Adjust the Trim pot until the desired output voltage is reached
  5. Turn off the digital output and connect the circuit to the the "Vout" and "GND" terminals
  6. Turn on the digital output again to power your circuit

Now that you have everything together, let's start using the PSU2001!

Phidget Control Panel

In order to demonstrate the functionality of the PSU2001, the Phidget Control Panel running on a Windows machine will be used.

The Phidget Control Panel is available for use on both macOS and Windows machines.


To open the Phidget Control Panel on Windows, find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the Ph.jpg icon to bring up the Phidget Control Panel.

For more information, take a look at the getting started guide for your operating system:

Linux users can follow the getting started with Linux guide and continue reading here for more information about the PSU2001.

First Look

After plugging the PSU2001 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Part 2: Using Your Phidget


The PSU2001 is a simple way to provide 1.5V - 5V DC power to a circuit or sensor. You interact with the PSU2001 through the Digital Output Channel Class to turn the power on and off. The output voltage can be adjusted using the trim pot.

Explore Your Phidget Channels Using The Control Panel

Double click on the Digital Output channel class under the port your PSU2001 is connected to.

Part 4: Advanced Topics and Troubleshooting

How do I know what channel, serial number, or hub port to use in my program?

Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.

1. Open the Control Panel and double-click on the red map pin icon:

The locate Phidget button is found in the device information box

2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
