Combine the Scoppy app with a Raspberry Pi Pico or Pico W to create a 500kS/s oscilloscope and 25MS/s logic analyzer.

Key Features:
- Wireless connectivity with the Pico W
- Horizontal scale and position adjustments
- Vertical scale and position adjustments
- Trigger channel and level selection
- Rising edge and falling edge triggers
- Auto and Normal triggering
- Continuous (Run) and Single capture modes
- Memory depth up to 100kpts for single captures
- Vertical and Horizontal Cursors
- Auto or fixed sample rate
- % pre-trigger samples setting
- Signal Generator
--- square wave (100Hz - 1.25MHz)
--- 1kHz PWM sine wave
- X-Y Mode
--- Hann, Hamming, Blackman and Rectangle windows
--- vertical and horizontal cursors
--- dBm, dBmV and V vertical units
--- option to display both channels simultaneously
--- option to display the scope window alongside the FFT
- Probe attenuation settings eg. 1X, 10X, custom

- Two Channels
- Up to 500k samples per second (shared between channels)
- Time/Div: 5us - 20secs
- Up to 4 configurable voltage ranges per channel (see help for details)

Logic Analyzer
- Eight Channels
- Up to 25M samples per second (per channel)
- Time/Div: 50ns - 100ms

Analog Front End
Connect the input signal directly to the Pico ADC pins for a 0-3.3V input range or build your own analog front end to extend the input range. Several cheap and easy to build open-source designs can be found at Affordable front ends are also available for purchase at
