The datasheet/pinout for the Nano Every shows A4/A5 as PA2/PA3, but from my reading of the ATMega4809 datasheet, these are not the I2C port that will also support the ADC. The code in pins_arduino.h suggests these are actually PF2/PF3 which does support both I2C and AIN12/13.

Similarly, for the Wifi Rev 2, A4/A5 are listed as PD4/PD5 (18/19) but the SDA/SCL additional pins are also listed as (18/19) but on PA2/PA3.

Is this correct?
