Be aware if buying Duet Wifi to be sent to Brazil

[brunofporto]

Our telecommunications agency, ANATEL, is now charging a very expensive tax for any radio emission device bought abroad. The Wifi module needs to be certified by the agency.

I am sure that ESP8266 is so there should be a way to work around this limitation.

I found this but I am not sure how to use it with Duet Wifi: https://fccid.io/ANATEL/04628-16-10018

This seems to be the certification: https://sistemas.anatel.gov.br/sgch/HistoricoCertificado/Homologacao.asp?NumRFGCT=1022217&idtHistoricoCert=10494805

But until that I would recommend for anyone buying from Brazil to choose the Ethernet version.
