Package List: 1 x GPIO Relay Module Note: Please use the power supply and load within the specified range, do not exceed the range. Rated load and lifespan are reference values and may vary significantly depending on the nature and type of load, so it is recommended to confirm through actual or simulated use. The load capacity of the module is greatly affected by ambient temperature and self heating, so it should be installed in an environment with good convection for heat dissipation. Electrical durability at high temperatures: When the module is used at high temperatures, the electrical durability may be lower than when used at room temperature, so please confirm during actual use.
