They are connected ​to the Microcontroller ports PB8 and PB9, and have 4.7kOhm pull-up resistors assembled. For high noise environments it might be required to add additional pull-up resistors, for example 2.2 or 1kOhm.
  
-Alternatively I2C port 2 can also be used. It is available on "Port Pins" 51 and 55(See [[#​pinout_diagram|Pinout Diagram]]). They are connected ​by the Microcontroller ports PB10 and PB11, and also have 4.7kOhm pull-up resistors assembled. Note that PB10 and PB11 are also used for programming if connecting this board to a programmer! They free when programming this board via the USB bootloader.+Alternatively I2C port 2 can also be used. It is available on "Port Pins" 51 and 55(See [[#​pinout_diagram|Pinout Diagram]]).
