Introduction:
This wheel is an unlicensed version of the new Nissan Nismo GT-R LM 2018 steering wheel.
Credit to the following people, I am thankful to you for the information you have all supplied to help me get to this level.
Wotever - Simhub. Without this software, this project wouldn't have gotten so far. Je vous remercie pour votre travail acharné.
Amstudio – your videos are the best. Great info on simhub setup wiring etc. You set a high standard!
Fox85 – Your MP4-12C GT3 wheel set the bar for 3d printed wheels! Thank you
Barry Rowland SimRacingGarage – Your reviews help define what level of detail goes into my efforts
As always .step files included for re-designing as you may see fit.
Part list is included with links for purchase.
You can find my Shifter in my other models.

Some words on wiring...
This was always the hardest part for me. Explaining it... even harder.
Take your time, especially with the usb wires. Getting these connected wrong can lead to all sorts of problems, burnt boards, things not working correctly, etc. Pay more attention than I did I and your build will go faster.
Certain things like the Nextion to USB-TTL board has an anomaly. The RX and TX MUST be connected to the OPPOSITE ie.
(Nextion lowercase, TTL uppercase) rx ==> TX and tx ==> RX .
Be sure to take note of the IN vs OUT wiring for the LEDS. Basic daisy chain.
The USB-TTL is easier to deal with if you remove the headers (connectors) and solder directly to the board as I have done in the pictures. Again, pay good attention to the usb wiring.
The Yoctopus Micro-USB-HubV2 is the magic that connects it all together. Purchase the cables from them as they also supply the connectors with the cable. Very difficult to solder the wires directly. I gave up and purchased the connectors. Still hard, but less impossible.
