[Tuya Smart] Switch & Temperature and Humidity Sensor

Overview

Tuya LOT switch & temperature and humidity sensor

> The lights at home are broken and keep flickering. So this time I replaced it with a smart switch.

> Of course, the way I dealt with the problem - I chose: cut the power cord of the light so that the light would stop flickering.

The external power supply module can be directly connected to the household circuit.
The power supply module can directly provide 5V and 3.3V, so I can omit the AMS1117-3.3 on the board. This project retains the corresponding circuit of AMS1117-3.3.
Reserved pads for 5V and 3.3V

The lamp current used to control does not exceed 700 ma, so the line width on the board is sufficient, and there is no need for tin plating or other measures to increase the current. QQ picture 20210201074434.png The project description is slowly being improved. . .
