SKW77 is a high power wifi router solution WIFI module. The module is compatible with 802.11b/g/n, RF using 2x2 MIMO, the highest rate up to 300Mbps. module internal integration of dual PA and LNA, each transmit output power up to +28dBm or more. The effective data transmission distance in the open area can reach more than 1000 meters, users can use it to easily achieve long-distance data transmission function.

The module adopts the 52pin dual-row pin mode, and the external power supply of +5.0V and +3.3V is required to power the external PA and the main system respectively. The module comes with its own operating system, which can be configured using the web page to achieve convenient and fast networking work.

The module interface supports USB, I2S, UART, SDIO, WAN, LAN, LED. external devices support USB slave devices, such as U disk, USB camera, etc.; support SD memory card; support I2S devices; support 1 WAN port and 2 LAN ports. Through the USB port can also be connected to the 4G module for 4G to wifi!
