## What it is
GP2040-CE is a multi-platform gamepad firmware for the Raspberry Pi Pico and other RP2040-based microcontroller boards, offering extremely low input latency and 14 input modes including XInput, Switch, PS4/PS5, and Xbox One. It includes a built-in embedded web configurator, RGB LED support, display support, and extensive customization features for building custom controllers and arcade sticks.

## Use cases
- build a custom arcade stick for fighting games
- convert a Raspberry Pi Pico into a low-latency gamepad
- make a controller that works on PC, PS5, Switch, and Xbox
- build a fightstick with SOCD cleaning for tournaments
- flash custom firmware with RGB LEDs and OLED display on a controller
- use a DIY controller on Steam Deck or MiSTer
- emulate keyboard inputs for MAME cabinets and rhythm games

## When to choose
- you are building a custom controller or arcade stick around an RP2040 board
- you need multi-console compatibility from a single device
- you want sub-1ms input latency for competitive play
- you want web-based configuration without installing software

## When to avoid
- your controller board does not use an RP2040 microcontroller
- you need native (non-passthrough) PS5 or Xbox One/Series authentication
- you want a plug-and-play commercial controller rather than a DIY build
