@felmue Thanks Felix for the reply. I wired the pin 27 for RX and now both RS-485 and I2C works fine.

Hi,
The RS-485 board of the LAN Module W5500 with POE works fine only
if the PORT.A.I2C of the CORE2 is not used. If the external I2C port
is in use the RS-485 communication looses the RX signal, because
of the G33 asignation for both purposes, RX and PA_SCL.
Somebody knows how to fix this?
Thanks!
