The Ethernet HAT we present today supports both 3.3V and 5V. The WIZnet product can simultaneously manage four independent hardware SOCKETs and provides 16 Kbyte internal memory for TX / RX buffers. WIZnet Ethernet HAT is designed for simple plug-and-play use. Used in conjunction with an RP2040 we will have a high-performance system, rich in memory and extremely small in size, able to access the network without problems.
Both the Ethernet HAT (about 6 euros) and the complete RP2040 system (about 12 euros) are available on the market.
