Scoppy Android app help

FHDM TECH Forum

• 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.

• Raspberry Pi Pico (or Pico W), Android device, header pins, BNC connectors and scope probes are NOT included

• Use of the second channel requires the premium version of the Scoppy Android app (approx US$2 in-app purchase)

• Wi-Fi functionality is only available with the Pico W (ie. not the Pico)

• Some assembly required

No. You can use dupont wires if you don't have probes.

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). When used with a Pico W, the Wi-Fi capabilities of the FSCOPE-500K allow the oscilloscope to be controlled from the Android device without a physical connection.
