About the i2c connection, I've a doubt about how doing it with I2C Expander to the er-301.
I will conect it in PORT A in backside.
And that case, How about voltages ? 3.3V or 5V ?
And How about the pullup ? ON or OFF ?
Is it OK that I conect it in PORT A with 3.3V , pullup ?

 Huh

3,3V pullup, port doesn’t matter and be sure you check the manual as there is more explanation on the ER301 setup.
