## What it is
Open FFBoard is open-source firmware for a universal force feedback interface and motor driver, designed for DIY simulation devices like direct-drive steering wheels and joysticks. It provides USB HID FFB device modes, multiple analog axis and button inputs, and is configured via a companion GUI.

## Use cases
- build a DIY direct drive force feedback steering wheel
- make a custom force feedback joystick for sim racing
- drive a stepper or servo motor as an FFB device
- replace expensive commercial FFB wheel bases with an open source alternative
- create a USB HID force feedback controller recognized by games
- add custom force feedback effects to a gamepad-style controller

## When to choose
- you are building your own sim racing wheel or FFB joystick hardware
- you want an open, highly configurable alternative to commercial FFB bases
- you need USB HID force feedback compatibility across many games
- you want a modular motor controller for stepper/servo FFB setups

## When to avoid
- you need plug-and-play consumer hardware with no DIY assembly
- you are a beginner uncomfortable with firmware flashing and hardware wiring
- you need guaranteed stability - the project is experimental and features may change
- you only need a simple non-FFB game controller
