W5500 Review: MEGA -based smart home wireless forwarding monitoring host

I am very happy after reading the official introduction, the new W5500 has been improved all the shortcomings of previous generations of  W5x00 … After continuously running of Web Server test program for an half hours later, I measured the temperature is always maintained at around 36 degrees Celsius, the fingers just feel it warm, that mean the power consumption has been decreased, only half of W5100 ; LQFP48 package is much easier for soldering , easier DIY my own modules ; chip temperature dropped almost cannot be felt … ”

After the releasing of W5500, it has been seen lot of user support and affirmation. As above is comment of the online user “sukeytang” after using W5100 and W5500. Please find below for the introduction of his application: MEGA -based smart home wireless forwarding monitoring host.
