Since the version that supports Ethernet module was only released in April 2019 (last year), if you bought your OS 3 after April last year you can purchase the module separately. Otherwise your controller most likely does not support Ethernet module. In any case, you can submit a support ticket with your order number so we can verify.
We are currently away till Friday, January 24. Any orders placed during this period will be shipped on Saturday, January 25. Thank you for your understanding! Dismiss
