## What it is
OpenSplitDeck is an open-source, modular wireless game controller inspired by the Steam Deck and Steam Controller, built from off-the-shelf parts, custom PCBs, and 3D-printed components. It uses nRF52840 microcontrollers with Enhanced ShockBurst wireless communication and custom IQS7211E trackpads, with firmware supporting gamepad, mouse, and keyboard HID modes.

## Use cases
- build your own steam deck-style controller
- diy wireless gamepad with trackpads
- open source hardware controller project
- custom controller with gyro and haptics for pc gaming
- modular detachable controller halves
- emulate a ds4 controller with custom hardware

## When to choose
- you want a fully open-source hardware and firmware controller you can build and modify yourself
- you want steam deck-like trackpads and gyro in a DIY wireless gamepad
- you enjoy 3D printing and soldering custom electronics projects

## When to avoid
- you need a polished, ready-to-use consumer controller out of the box
- you cannot solder, flash firmware, or 3D print parts
- you need guaranteed stability - the project is early stage with breaking changes and incomplete features like keyboard/mouse HID modes
