Naming rules

  • 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 WBLC9 as an example, W (Wi-Fi) + B (Bluetooth) + LC (light control).

Model selection

Tuya provides a variety of modules designed for different applications and specifications. For more information, visit Solution Center.

This section uses the filament lamp as an example to describe how to select an appropriate module for your product.

Parameters Description Applicability
Protocol If your product is designed for residential homes where a wireless router is typically used, choose Wi-Fi or Wi-Fi and Bluetooth combo protocol. Wi-Fi module or Wi-Fi and Bluetooth combo module
Size The PCB is mounted in the lamp socket, requiring a compact module. CoB solution, LC5, LC6, LC8, LC9, and 15 series
Antenna types The PCB is mounted in the lamp socket, requiring an external antenna with an adjustable structure. Modules connected to an external monopole antenna
Operating temperature The operating environment for filament lamps usually exceeds 85°C, requiring the module to be resistant to high temperatures. L series or LC series

Considering the above factors, WBLC5 series is the appropriate choice.

Development method

No-code development

On the Tuya IoT Development Platform, create a product with a no-code solution, select the desired module, and configure the firmware without coding. A ready-to-use module that is flashed with your defined firmware will be delivered to you. For more information, see No-Code Development.

Low-code development

On the Tuya IoT Development Platform, create a product with a custom solution, choose MCU SDK for the development method, and flash the generic firmware to the module to enable your MCU to communicate with Tuya’s module. For more information, see MCU Low-Code Development.

TuyaOS development

On the Tuya IoT Development Platform, create a product with a custom solution, choose TuyaOS for the development method, and flash your firmware implementation to the module. For more information, see What is TuyaOS?.
