Description

The goal was to create a 230V board that would switch other 230V devices via a relay.

The board also contains a thermometer and a light sensor. The whole thing is connected to ESP8266 D1 mini.
There is also independent cooling on the board. The fan should turn on based on the set temperature.
There are also a couple of connectors for other modules.

The expected operating temperature is -20 to +70 degrees Celsius.

The plate may occur in a humid environment.

The board should be for commercial use.
