FScope-500k

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.
