SIM Race PRO - Wheel and Additional Modules

*** Update 15/12/2025 (see below) ***

The SIM Race PRO is a modular driving sim with a force feedback system that lets you enjoy your favorite racing games.

Start at the level you want and then update your SIM Race PRO later.

In this model, you will find all the files you need to build the SIM Race PRO wheel. You can build it in the standard version or in the PCB version. There are two separate tutorials, and the difference between the two versions is only in the wheel_box (which obviously has supports for all components in the version without PCB and instead has supports for the PCB only).

Assembly Guide

To build the SIM Race PRO Wheel, you can follow the videos tutorials below. If you need help, I can assist you on my official Discord channel.

For the pin diagram and the general electrical diagram follow the schematics in the shared drive dir.

BOM for purchasing components + Electrical diagrams

You will find the list of necessary components and electrical diagrams in an update for backers only on the crowdfunding campaign page in the updates section.

Software Tutorial

In the following link, you will find all the scripts you need to run your SIM Race PRO. You can find a short tutorial in the readme file or watch the following video for all the necessary steps. 

• Release v1.0.0
• Release v2.0.0

Additional Modules

On this page, you will also find all the wheel box pcb version, the additional handbrake and manual transmission modules. You can find the files in the print profiles section. You can find the video tutorials in the next section.

Additional Modules Assembly Guide

Below you can find the tutorial for the wheel_pcb assembly, in the drive shared directory (link in the update for backers only) you'll find all the schematics for the elettronics.

All the files for order the PCB are in the shared drive dir.

Tip on assembling the Custom Wheel PCB: you will need to insert a small piece of electrical tape or even a piece of heat-shrink tubing between the pins of the two central LEDs and the Arduino pins to prevent them from touching.

Below the Handbrake Module Assembly video. Note that the handbrake is binded with the keyboard spacebar.

Below the Manual Trasmission Module Assembly video. Note that the gear are binded with the keyboard number 1…6.

Conclusion

I hope you like this project. Let me know what you think in the comments and any suggestions and/or improvements are welcome 🚀✌️

Updates
