Description: 1. The 1 CH 5V Active Low Relay Board is a single-channel electronic relay module designed for controlling electrical loads of up to 5V and 300mA. 2. Features: It comes with an integrated microcontroller that can be controlled via TTL or RS-485 signals, providing flexibility in various applications. The board also includes diode protection for the input signal against reversed voltage. 3. Functionality: This relay module is ideal for controlling appliances, solenoids, and other low power loads through digital signals from a microcontroller or a computer. It functions as an electromechanical switch that opens when the input signal goes high and closes when it goes low (active low). 4. Versatility: The board can be used in various IoT projects such as home automation, industrial control systems, security systems, and laboratory experiments where there is a need to switch electrical loads remotely or automatically. 5. Operating Conditions: It operates efficiently within the temperatu
