Tuya smart single socket

Use WR3E WiFi module as the main control. WR3E is a low-power embedded Wi-Fi module developed by Tuya Smart. It consists of a highly integrated wireless radio frequency chip RTL8710BN and an external flash chip. It has a built-in Wi-Fi network protocol stack and rich library functions. It also has a built-in low-power 32-bit CPU that can double as an application processor. Working voltage: 3V-3.6V. By using the built-in firmware of WR3E, the entire IoT module can easily interact with Tuya Cloud. Based on these, you can develop embedded Wi-Fi products that meet your own needs. 

You want to use Tuya’s products, but are you still spending money to buy finished products? You only need the money for the module to customize the hardware yourself!

step

1. Log in to the Tuya Smart IoT platform to create a category "socket" and choose the development-free plan;
2. Draw the schematic diagram + PCB diagram according to the module function, and make the board;
3. Welding debugging. . . (I found that the schematic diagram given by Tuya is the default. Even if the pin definition diagram is changed, it will not change. It can only be solved by flying wires. The current version has been corrected)

Put in the shell, punch holes, and call it a day! The functions of the device are the same as those of sockets purchased online, including switches, countdowns, child locks, and inching cycles ;
