INTRODUCTION
DFRobot
WiFi Shield for Arduino, 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.
