Introduction

The shield uses WizFi210 which is a low power-consuming WIFI module which is applied with dynamic power management technology. When the WIFI module needs to be on but not work, it can be set to Standby mode a low power mode, and the module just needs to be woken up when it has to work.

The WIFI wireless module is based on WizFi210. It provides the bridging from TTL serial port communication to IEEE802.11b/g/n wireless communication. So any device with TTL serial ports can easily be connected with this WIFI module and controlled and managed remotely through a wireless network. Different kinds of communication protocols and encryption algorithms are integrated with the module. The Arduino architecture enables you to easily integrate this module into any Arduino based project.
