What interfaces are commonly used in embedded systems? UART, SPI, IIC or USB, CAN?

Common communication interfaces of WiFi module are: USB, SDIO, SPI (slave), UART, RGMII and RMII. According to the interface classification, SKYLABWiFi modules can be roughly divided into four categories, namely USB interface WiFi module, Ethernet interface, serial port WiFi module UART interface and Bluetooth two-in-one WiFi module. Commonly used communication interfaces and WiFi module models are as follows:

1)USB interface wifi module:

Wifi modules from USB interface: SKW 17AE, WG209, WG2 17, WG233；;

Main mode USB interface wifi modules: SKW77, SKW78, SKW92A, SKW92B, SKW93A, SKW95, SKW97, SKW99, SKW 100, SKW 103, etc.

2)UART serial interface (serial port) wifi module:

Wifi modules of the Internet of Things: WG2 19, WG229, WG23 1, LCS6260；;

Wifi and Bluetooth two-in-one modules of the Internet of Things: WG222, LCS2028, WG235, WG236 and WG238.

3)SDIO interface wifi module: wifi Bluetooth two-in-one module WG225 and WG244.

4) Ethernet port (RJ-45 interface) wifi module:

100 gigabit Ethernet wifi modules: SKW77, SKW92A, SKW92B, SKW93A, SKW95, SKW97, SKW99, SKW 100, skw103; ;

Gigabit Ethernet port wifi module: SKW78.
