Congratulations to the Arduino team for the Arduino ARM monster! I want to build my own W5100 and Arduino network card. Using 3v3 at the uP I need to install the voltage level-converter for the SPI port? If the response is yes, what are those devices that can run this function? Best Regards!! Fr…

Using the W5100 at 3V3 P.S.. needs SPI voltage buffers/level converter?
