## What it is
A community documentation repository of reverse engineering findings about the Nintendo Switch and Joy-Con controllers, including PCB layouts, pinouts, SPI bus captures, and sensor details. It serves as reference material rather than runnable software, with some C code and logic analyzer captures.

## Use cases
- understand how Joy-Con controllers communicate with the Switch
- find Joy-Con PCB pinouts and test points
- build custom software that reads Joy-Con input
- learn about the Joy-Con accelerometer and gyroscope configuration
- reverse engineer Nintendo Switch controller protocols
- spoof or emulate Joy-Con button presses

## When to choose
- you want documented hardware details and protocol findings for Joy-Con or the Switch
- you are hacking on Joy-Con hardware or writing custom controller drivers
- you need reference material for Switch controller research

## When to avoid
- you need a ready-made, supported Joy-Con driver library
- you want polished software with a license and stable API
- you are looking for general game development tools

## Facets
- artifact type: learning-resource
- maturity: active
- function: reverse-engineering, documentation, embedded
- domain: hardware, reverse-engineering, gaming-tools, developer-tools
- platform: embedded, cross-platform
- tags: nintendo-switch, joycon, hardware-hacking, protocol-analysis, bluetooth-hid, teardown
