EMS WiFi Shield is a WiFi shield module for DT-AVR Inoduino or another Arduino module. This module has UART interface to comunicate with host controller.

EMS WiFI Shield work at 2,4GHz with +18dBm power output. The range of this module is highly dependent on the signal strength of WiFi Module is connected, such as WiFi router, Smart Phone (Android). This module also provide security feature, such as WEP-128, WPA-PSK(TKIP) and WPA2-PSK(AES).

EMS WiFi Shield has compatible layout pin with Arduino, so this module can be used on wide various of Arduino modules or Arduino compatible modules, such as DT-AVR Inoduino, DT-AVR Leoduino, DT-AVR Unoduino, DT-AVR Maxiduino, Arduino UNO, Mega, and Leonardo.

Dimension : 5,45 cm (L) x 5,4 cm (W) x 2 cm (H)
