Стыдно спросить, как им пользоваться?
Это вроде WiFi-модуля, который надо подключать к контроллеру, или он может выполнять IoT-задачи сам по себе, крутить внутри себя какой-то код?

Product introduction:
The Wi-Fi module, also known as the serial port Wi-Fi module, belongs to the transmission layer of the Internet of Things. Its function is to convert the serial port or TTL level into an embedded module that conforms to the Wi-Fi wireless network communication standard. The built-in wireless network protocol IEEE802.11b.gn Protocol stack and TCP/IP protocol stack. Traditional hardware devices embedded in Wi-Fi modules can directly use Wi-Fi to connect to the Internet, which is an important part of realizing wireless smart home, M2M and other Internet of Things applications.
