The official OpenFFBoard project server.
The OpenFFBoard project is a highly customisable open source project for building DIY force feedback devices like steering wheels for simracing.
It is mainly a firmware but also contains dedicated hardware for interfacing different motor drivers as well as an official TMC4671 based motor driver designed specifically for FFB.
In this server you can discuss DIY FFB setups, get help from other users and participate in the development of the project and get early updates.
