tuya IoT interface WP1354

Tuya IoT inteface

From manufacturing company (Whadda) documentation:

Control your Arduino projects from anywhere in the world with a free app thanks to the Tuya IoT interface!

Plug the Tuya IoT interface module into your Arduino by using the included 4 male wires. Then connect your Arduino with the IoT Tuya cloud by simply installing the Tuyav library, which is compatible with ATmega chipsets (or AVR platforming). This will enable you to connect with the Tuya app over WiFi and lets you control up to 5 outputs.

This description is correct but limited. As in Tuya documentation, a Tuya device is the union of two modules:

The MCU can be any thing that can talk via serial protocol to WiFi module. This way it is possible to build 'real' custom Tuya devices!
