## What it is
Scoppy turns a Raspberry Pi Pico and an Android phone or tablet into a low-cost oscilloscope and logic analyzer. The Pico firmware samples signals (up to 2MS/s analog, 25MS/s logic) and the Android app displays the waveforms over USB or Wi-Fi.

## Use cases
- turn my android phone into an oscilloscope
- cheap logic analyzer for hobby electronics
- view low frequency signals with a raspberry pi pico
- debug arduino or microcontroller circuits without buying a scope
- wireless oscilloscope using pico w over wifi
- teach electronics students signal measurement on a budget
- measure 0-3.3v signals with a pico and usb otg

## When to choose
- you already own a Raspberry Pi Pico and an Android device and want an ultra-cheap scope
- you're a hobbyist, novice, or STEM student viewing low-voltage, low-frequency signals
- you want a logic analyzer up to 25MS/s without buying dedicated test equipment
- you want a setup that requires no programming and installs in minutes

## When to avoid
- you need professional-grade bandwidth, accuracy, or isolation for high-voltage work
- you don't have an Android device supporting USB OTG (or a Pico W for Wi-Fi)
- you need an oscilloscope for high-frequency signals beyond 2MS/s
- you require official support on non-Android platforms like Windows or iOS

## Facets
- artifact type: application
- maturity: active
- function: data-visualization, embedded
- domain: embedded-systems, hardware, education, developer-tools
- platform: embedded, cross-platform
- tags: oscilloscope, logic-analyzer, raspberry-pi-pico, electronics, stem, test-equipment, usb-otg, wifi, android
