=== I2C design rules===
*I2C0 should be your default option, but it could be interesting use Optional I2Cs if your external peripheral need needs to use a huge transfer data connection.
*Optional I2Cs needs to be pulled up externally, 5K resistor tied to 3V3 must be necessary.
*IGEP COM AQUILA uses 3V3 voltage levels for I2C buses. In some cases, voltage translators like TXS0102 should be necessary to adapt voltage levels between ICs.
