Wiznet W5500 and ioShield-A What’s old is new again!

Thanks feilipu for the comparison of our new W5500 within our growing WIZnet chip family, JoW

It seems that the Wiznet W5100 Ethernet Shield has been around since the very beginning of the Arduino movement. Its integrated TCP and UDP IP stack enabling solid standardised networking since the very beginning.

The hardware implementation of BSD sockets interface abstracted the complex process of generating compliant IP and made sure that it was done correctly, and the buffering of network packets in integrated packet RAM, rather than on the host AVR micro-controller; was a great thing when you only have 1kB of RAM available as the original ATmega168 Arduino devices provided. For the current generation of Arduino devices, nothing has really changed.

Recently, I wrote about the new W5200 iteration of the Wiznet integrated IP controller, and how it is significantly better in performance and features than the older W5100 version.

Now, I have my hands on the latest version. The W5500 on an ioShield-A from Wiznet.
