FScope-500k DIY OsCILlOsCOPE

Combine the FSCOPE-500K with a Raspberry Pi Pico or Pico W* and the Scoppy Android app* to create a 500kS/s oscilloscope.

Simply solder a Pico (or Pico W) to the board together with 0.1" header pins and the supplied trimmer capacitors and you have a 500kS/s oscilloscope.

The FSCOPE-500K is also available fully assembled. See the DSO-500K product page for more information.

Do I need oscilloscope probes to use the FSCOPE-500K?

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

PayPal tells me that you don't ship to my country even though you show a price for shipping here. What can I do?

PayPal sometimes gets temporarily confused! Try again later and/or use a different device when you make the purchase.

How can I purchase more than one FSCOPE-500K pack at a time?

Send an email to store@fhdm.xyz including your country and the number of FSCOPE-500K packs you wish to purchase. We will reply with a quote. 

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). 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. For pricing of classroom sets of more than 20 boards please contact us at store@fhdm.xyz
