Description

WiFi Shield V3 PCB Antenna Arduino Shield

INTRODUCTION
DFRobot WiFi Shield, is part of our wireless family product. This WIFI Shield V3
supports AP + STA dual mode, and is extremely easy to connect to a home
router network. You only need a mobile phone or Pad to log in the AP network of
this module (similar way with some router configuration tool). After logging in the
module and set the Wireless name, it is ready to connect the WIFI network 
(No AT command setup required, which is often very complex).
 
This module uses dynamic power management to achieve low power consumption
capability (standby: <80uA; normal mode average: 8mA; peak: 200mA). This is
especially useful in prototyping which not only demands low power consumption,
but also requires a standby mode. The module provides UART(TTL) to
IEEE802.11b/g/n wireless communication. IEEE802.11n is a newest wireless 
transmission protocol which features higher transmission speed, wider coverage,
stronger compatibility and much more reliability. Currently many wireless electronic
equipment manufacturers have been applying this standard (IEEE802.11n) to a large
number of products. With this WIFI Shield, any device with UART can easily set up
a wireless network and achieve remote management and controlling. This is an
excellent choice for those with wireless communication compatibility issue.
