Hi,
I would like to have microcontroller module with following features:
1. Can be programmed in Arduino IDE
2. Has Ethernet connectivity
3. Can use MOD-RS485 UEXT module
4. Can use MOD-IO2 UEXT module
Can somebody please recommend board with features listed above? Thx.
On-board Ethernet is huge problem for common Arduino AVR boards like OLIMEXINO-2560. Maybe consider an ESP32 board like:

These boards also have extra WIFI. They can be programmed via Arduino. Have enough GPIOs to add MOD-IO2 and MOD-RS485.
