FScope-500k DIY OsCILlOsCOPE KIT
Build your very own oscilloscope with the FSCOPE-500K Oscilloscope Kit. The kit includes everything you need to build a 500kS/s dual channel* oscilloscope.
The oscilloscope connects to your Android device and displays the waveform data using the highly rated Scoppy Android app (connection to the Android device is via Wi-Fi or USB).
Our kit includes the FSCOPE-500K oscilloscope board, a Rasperry Pi Pico W, trimmer capacitors, pin headers and sockets, jumpers and plastic feet.
Please note that oscillscope probes are not included but dupont wires can be used instead.

What You'll Need
An Android device that's running Android version 6.0 (Marshmallow) or higher. 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 (not supplied). Even if you are planning to use Wi-Fi, we recommend having a compatible OTG (On-The-Go) cable so you can access the firmware settings in the event you can't connect via Wi-Fi (eg. if your Wi-Fi password changes or the Wi-Fi settings in the firmware were entered incorrectly). The OTG adapter plugs into the USB port of your Android device.
Please Note
Scope probes are NOT included
Use of the second channel requires the premium version of the Scoppy Android app (approx US$3 in-app purchase)

FAQ
Do I need oscilloscope probes to use the FSCOPE-500K Kit?
No. You can use dupont wires if you don't have probes.
Is the FSCOPE-500K suitable for use in the classroom as part of a STEM curriculum?
Yes, the FSCOPE-500K has been specifically designed to work with low voltage circuits typically used in STEM education. Once assembled, the FSCOPE-500K has many of the features of a benchtop oscilloscope but at a fraction of the price (eg. FFT, X-Y mode, cursors). The Wi-Fi capabilities of the FSCOPE-500K KIT allow the oscilloscope to be controlled from the Android device without a physical connection.
