GWF-KM22 module applies a highly integrated MAC/BBP in the MT7681 chipset, and support IEEE 802.11b/g/n standards with 1T1R technology

About this Solution:

Shenzhen Ogemray Technology Co. Ltd. was established in 2004, focus on radio frequency, WiFi ,wireless Transmission,and intelligent applications.


GWF-KM22 Ogemray WiFi Smart Module MT7681 Chipset-


The GWF-KM22 module operates in 2.4GHz ISM frequency band with low power consumption; it applies a highly integrated MAC/BBP in the MT7681 chipset, support IEEE的802.11b/g/n standards with 1T1R technology.

This module supports TCP/IP,UDP protocol,its low cost and low power consumption, easy using characteristics make the wireless connection become easy and reliable.

The single side components mounted module provide 1 UART interface and 4 GPIO ports. The optional on-board or external antenna easy the downstream RF hardware technology requirement. A set of future provided serial AT commands can simplify software design, thus a normal, simple, cheap MCU can be used to control the WiFi module easily.

The module includes a number of TCP/IP-based connectivity protocols enabling a low-cost, low-complexity system to contain full-featured internet connectivity and reliable information exchange.This module is mainly used in a multitude of smart home appliances and consumer electronics such as remote control, thermostats, power socket, WIFI audio transmission, LED control, wireless sensor, etc and other applications.
