Thank you Cefiar your answers were very clear! I'm not a genius at electronics, I like to solder and build little circuits but I understand what you said.
So for the logic leveler should I use a circuit like that, right? [www.sparkfun.com]
Can I use the same circuit with the servos logic? You told me about the 4 outputs at 3.3v.
[Edit] I forgot to tell you, about the latency of the TB driver, in the comments of the YouTube video there's an explanation about using the capacitor to level the micro timing signals, also they talk about Marlin.
For the expansion board, you said what I had in mind; write the code into both of MCUs boards. I need to command also electromagnets that works with 12v, my idea is to use an Arduino board (connected thru SPI) with a relays shield to turn on/off magnets' states.
Thanks again.
