SKYLAB IOT WiFi Module SKW92A has two model type :SKW92A and SKW92B , the two wifi module size is the same , and the shape only has a IPEX difference , so some customer will ask : what is the difference between them ？
Data Rate :SKW92A is 2×2 MIMO WiFi Module , the data rate is 300Mbps , but SKW92B data rate is 150Mbps.
Chip : SKW92A are based on MT7628N , and SKW92B are based on MT7688A
Interface :SKW92 WiFi module has many interfaces (I²C, PCM, I²S(192K/24bits), PWM, SPI slave, UART lite, GPIO), the interface is the same between SKW92A and SKW92B , SKW92A has 3 UART,1 WAN and 4 LAN , but SKW92B has 2 UART , 4 WAN and 4 LAN .
Power Consumption : SKW92B is the more power saving than SKW92A , SKW92A continuous receiving current is 230mA , and SKW92B is 95mA .
