No, Phidgets require usb connection to a computer with a USB host controller and running Windows, macOS, or Linux. If you want something portable, the best option is a PhidgetSBC or Raspberry Pi.
However I think that the API library of the Phidgets send with a Serial over USB the commands from the PC to the controller.
There is a list of these commands?
Is just a my idea that Phidget uses a serial-over-usb communication.
My idea comes from the fact that many devices generally work like this.
Sorry about that.
