Scoppy Android app help

THE DSO-500K-U HAS BEEN RETIRED AND IS NO LONGER AVAILABLE. PLEASE SEE OUR DSO-500K PRODUCT PAGE.

• An Android device that's running Android version 6.0 (Marshmallow) or higher with version 1.026 or higher of the Scoppy app installed. 

• The device must also support USB OTG (On-The-Go) - most modern phones/tablets do. If you are able to install the Scoppy app from the Play Store then (Google thinks) it does support USB OTG.

• A compatible OTG cable/adapter. The OTG adapter plugs into the USB port of your Android device.

• Android device, USB cables, scope probes, BNC connectors and OTG adapter are NOT included (the latter 3 items can be supplied if you purchase the DSO500K-U at our Tindie store).

You can use dupont wires as probes. BNC connectors (not supplied) can be soldered on to the DSO500K-U for use with standard oscilloscope probes. See the operating instructions for details.

The DSO-500K supports wireless and USB connectivity with your Android device. The DSO500K-U only supports USB.

The DSO-500K includes BNC connectors, the DSO500K-U does not (BNC connectors can easily be soldered to the board).

Yes, the DSO-500K has been specifically designed to work with low voltage circuits typically used in STEM education. The DSO500K-U has many of the features of a benchtop oscilloscope but at a fraction of the price (eg. FFT, X-Y mode, cursors). For pricing of classroom sets, please contact us at store@fhdm.xyz
