## What it is
An open-source 24-channel, 100Msps logic analyzer combining custom hardware (based on Raspberry Pi Pico) with Python-based capture and analysis software. It supports Sigrok protocol decoders, auto-detection of devices, and both GUI and terminal capture applications.

## Use cases
- capture and decode digital signals from embedded devices
- debug SPI, I2C, or UART communication between chips
- reverse engineer protocols on retro computers like the ZX Spectrum
- view timing of GPIO signals with a logic analyzer on a budget
- record 24-channel digital captures at 100Msps
- decode bus traffic using Sigrok protocol decoders

## When to choose
- you need a low-cost, open-source logic analyzer with many channels
- you want Sigrok decoder support with a modern Python-based UI
- you are comfortable building or ordering the companion hardware

## When to avoid
- you need a commercial-grade analyzer with warranty and support
- you require sample rates or channel counts beyond 100Msps/24 channels
- you want plug-and-play hardware without assembly or ordering from PCBWay

## Facets
