Industrial-Grade TT-24L-SKB_V01A IoT Main Control Switch Board
I. Wi-Fi Module:
The Guangxi Tongtai Communications Wi-Fi module is a proprietary product developed to meet the needs of various application scenarios and functional requirements. It receives or transmits wireless signals via an antenna; the RF circuitry converts these signals into digital signals or performs the reverse conversion, after which the baseband processor handles encoding, decoding, and other processing tasks, while the microcontroller manages the module’s operational status. It can connect to routers or hotspots via the Wi-Fi protocol. It supports the TCP/IP protocol stack and can transmit various types of data. It also supports network configuration methods such as static IP and DHCP (automatic IP acquisition), as well as security encryption methods including WEP, WPA, and WPA2.
II. Main Types
• General-purpose Wi-Fi modules: Require use with a host controller chip; provide full Wi-Fi functionality; used in smart home appliances, industrial control, and other fields.
• SoC-type Wi-Fi modules: Integrate an MCU and Wi-Fi functionality; can run programs independently; suitable for low-cost IoT devices.
• Embedded Wi-Fi modules: Compact and low-power; directly embedded into circuit boards; commonly used in wearable devices and medical equipment.
• High-Power Wi-Fi Modules: Support long-range transmission and are suitable for outdoor scenarios.
III. Application Scenarios:
Widely used in smart homes, industrial IoT, agricultural monitoring, consumer electronics, medical devices, and other fields to enable functions such as remote device control and data transmission.
