AZL WIFI SHIELD RN171

SKU: AZL WIFI SHIELD RN171

BRAND: Communica


WiFi Shield utilizes a RN171 TCP/IP Wireless Network Module with an on-board Micro SD slot

Overview

This Wifi Shield utilizes a RN171 wifi module to provide your Arduino/Crowduino with serial Ethernet's function and adds storage to your arduino project . It features an independent antenna which can cover a wider range and transmit stronger signals. With supports for common TCP, UDP and FTP communication protocols, this Wifi Shield can meet needs of most wireless network projects, like smart home networks, robot controls or personal weather stations, etc. We prepared an easy and convenient command set for this shield so that you can use neat and concise code to run the function. If you use the wifi function, it takes two pins to hook your device up to 802.11b/g wireless networks. If you use the storage, it takes SPI and a select pin to access to the SD.
