DIY Porsche GT3 buttonbox for simracing

Made this a while ago for myself.

I wanted it to look like the Porsche GT3 buttonbox and a bit like the one from Fanatec with a screen. It had to fit a d-shape wheel from OMP or Motamec or a cheap aliexpress wheel.

So i made one that would fit a 0,96" oled screen.

For this build you need 2 arduino's because the oled needs a lot of frame buffers.
Also use a Nano for it. For the buttons you could use a Pro Micro.
On how to use the screen look at here:

To use 2 arduino with only one usb. Use one of these hubs:
