Tuya provides a series of proprietary network modules with various specifications and methods of soldering to address different needs of IoT product development. The network modules can apply to a wide range of IoT wireless communication or voice-control applications to help you develop your ideas faster and get your product to market sooner. This topic describes the types of network modules in terms of protocols, naming rules, features, and development methods. You can visit Solution Center to explore more details.
According to the network coverage, network modules can be broken down into two types: local area network (LAN) modules and wide area network (WAN) modules.
The following table lists the protocols available to these two types of network modules.
|2.4 GHz Wi-Fi||Standard 2.4 GHz Wi-Fi||Communication over 2.4 GHz Wi-Fi network.|
|Low power Wi-Fi||Low power 2.4 GHz Wi-Fi||Communication over 2.4 GHz Wi-Fi network with low power consumption. It is suitable for products typically powered by batteries.|

The naming rule for generic modules: (TY) + wireless protocol + chip’s name + series + performance.
Take TYWE3S as an example, TY (Tuya Smart) + W (Wi-Fi) + E (Espressif) + 3 (3 series) + S (high performance).
The naming rule for specific modules: wireless protocol + chip’s name + distinguished name.
Take CBLC9 as an example, C (Wi-Fi and Bluetooth LE combo) + B (Beken) + LC (light control).
