Review - WIZnet WIZwiki-W7500
The WIZwiki-W7500 board is a rapid prototyping platform for IoT and secure networking applications. It is based on the WIZnet W7500 chip that integrates a 32-bit ARM Cortex-M0 core, 128 KB Flash memory and a hardwired TCP/IP stack. Also in the chip is 16 KB RAM (+ 32 KB for the TCP/IP stack that can be added to the system RAM), an MII Interface (for an Ethernet PHY chip), 53 GPIO ports, an 8-channel ADC, three UARTs, two SPI ports and two I²C ports. The TCP/IP stack has an integrated Ethernet MAC and handles the protocols TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE.

On the board are Arduino shield extension connectors (including the 6-pin SPI/ISP connector), a 10/100 base-T Ethernet port with RJ45 socket, an mbed interface for drag-n-drop programming and serial communications over USB, and a micro SD card slot. An 18-way connector gives access to some more GPIO pins and an RGB LED is available as a (bright) visual indicator.

The WIZwiki-W7500 mbed Starter Kit consists of a WIZwiki-W7500 board plus cables and two small breadboards, LEDs, resistors and some other stuff.

There is also a WIZwiki-W7500P board, which is very similar, except that it is built around a W7500P chip which integrates the Ethernet PHY (and has less GPIO, 34 instead of 53). This board has additional extension connectors for an XBee module.

Finally, the WIZwiki-W7500ECO is like a WIZwiki-W7500 but smaller and with fewer connectors, intended for integration in a system or for use on a breadboard.
