For ARDUINO AVR:

Pin MDIO - D6 (Logic Level convertor 5v-to-3.3v pin MDIO on switch) Pin MDC - D5 (Logic Level convertor 5v-to-3.3v pin MDC on switch) Pin GND - D7 (only used as for fastening to the switch board)

For ARDUINO STM32:

No need Logic Level Convertor, use pin-to-pin conection and pullup 10K resistors (between the pins and 3.3v from the switch board).

Pin MDIO - PB10 (and used as for fastening to the switch board) Pin MDC - PB11 (and used as for fastening to the switch board)
