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 enjoys features such as higher transmission speed, wider coverage, stronger compatibility, and greater safety. 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.
