W7500 based ARM® mbed Platform Board for IoT
Product Overview

WIZnet WIZwiki-W7500 is a WIZwiki platform board based on W7500. The IOP4IoT W7500 chip is one-chip solution which integrates an ARM Cortex-M0, 128KB Flash and hardwired TCP/IP core for various embedded application platform especially internet of things. If you use WIZwiki-W7500, you will be able to easily develop a prototype. It is compatible with Arduino Shields. This is using the CMSIS-DAP USB and ISP Header easily available firmware writing.
