Adapter G27 và button box 4x4 (g27 adaptor and 4x4 button box)

button box for truck sim no code yet created 
you can refer to Odevsa model for the code on thier model and Ranppa for the face plate on this

just creating a button box for the ETS mainly but since modeling side is done i think its good for me to share this for everyone to help me if you can 

additionally i use a Arduino pro micro c i created the holes extra large in case there's a possibility to use something like micro usb or type b 

i just use some cheap db9 connector which is extremely large if you can find a smaller break out board or just solder directly that will largely benefit you but this model is more life fail safe method just for me to use the shifter and pedal while I'm figuring out the button box

please bear with possible miss alignment specially for the DB9
