I am using a Arduino Micro Pro in my new 3D printed sim-wheel with buttons, LED strip, LCD, etc.
Unfortunately this board has got to little number of connections. The question raised if it is possible to connect two Mirco Pro’s on one USB connection?
Excuse me if this is a stupid question, I am new at this game.
No.
One USB connector one USB device ONLY
To get more pins the use some sort of port exapander. The simplest is probbly a serial shift register.
See this link for how to.
The same technique will work for any Arduino.
