Buy
THE DSO-500K-U HAS BEEN RETIRED AND IS NO LONGER AVAILABLE. PLEASE SEE OUR DSO-500K PRODUCT PAGE.
What You'll Need
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.
Please Note
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).

FAQ
What type of probes do I need to use with the DSO500K-U?
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.
What is the difference between the DSO-500K and the DSO500K-U?
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).
Is the DSO500K-U suitable for use in the classroom as part of a STEM curriculum?
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
