## What it is
A Windows desktop application for managing, inspecting, and customizing Nintendo Switch Joy-Con controllers over Bluetooth HID. It provides tools for firmware updates, input testing, calibration, and protocol-level control of the controllers.

## Use cases
- update Joy-Con firmware from a PC
- test and calibrate Joy-Con stick drift
- change Joy-Con LED and color settings
- inspect raw HID packets from Joy-Con controllers
- pair and manage Switch controllers on Windows

## When to choose
- you need to manage or repair Nintendo Switch Joy-Con controllers from Windows
- you want to update controller firmware without a Switch console
- you are reverse-engineering the Joy-Con HID protocol

## When to avoid
- you are on Linux or macOS
- you need support for non-Switch controllers
- you want an actively developed tool with frequent updates

## Facets
- artifact type: application
- maturity: maintenance
- function: gui, reverse-engineering, developer-tools
- domain: hardware, gaming-tools, reverse-engineering, windows
- platform: windows
- tags: joy-con, nintendo-switch, hid, controller-tools, firmware, desktop
