This product is a wireless network card module with RTL8188CUS chip, low power consumption, high linear output power, and 150M USB interface. Comply with IEEE802.11n standard, compatible with IEEE802.11g, IEEE802.11b standard, provide USB2.0 interface, compatible with USB1.1/2.0. Support the latest 64/128 bit WEP data encryption; support WPA-PSK/WPA2-PSK, WPA/WPA2 security mechanism. Using 11N transmission technology, up to 150Mbps wireless transmission rate. It is 10 times that of ordinary 11B products. It has a built-in omnidirectional ceramic antenna, and an external antenna can be used to make the transmission distance longer, and it can communicate with other wireless devices that meet this standard. It can adapt to different working environments, so that desktop computers, notebook computers, tablet computers, network cameras, set-top boxes, GPS and other devices that need to achieve wireless networking can easily access the wireless network. 

Note: This module can choose 5V power supply.

This module is a compatible design with built-in antenna and external antenna. Customers can directly use the ceramic antenna in the board when using it, or through an external cable with higher gain.

This WIFI module is suitable for: desktop computers, notebook computers, netbooks, MID tablets, digital photo frames, network TV set-top boxes, network cameras, network high-definition players, Android network players, Android smart TV boxes, etc.

Support Windows2000/XP/Vista/Windows 7/LINUX/WIN CE/MAC OS/Android and other operating systems.
