Description: 1. Overview: The 2-Channel 5V Relay Board is a versatile IoT component designed to control electrical appliances or circuits using low voltage signals. Each channel can handle up to 30A / 250VAC load. 2. Design and Compatibility: It features two opto-isolated relays with separate NO/NC pins for each channel, ensuring safety and reliability in various applications. This board is compatible with most microcontrollers and development boards through its common IO interfaces (3.3V or 5V logic levels). 3. Opto-Isolation: The use of opto-isolated relays provides several benefits such as galvanic isolation between control signals and the load circuit, eliminating electrical noise, and providing protection against voltage surges and short circuits. 4. Versatile Applications: Common applications for this relay board include controlling lights, fans, motors, pumps, and solenoids in IoT projects like home automation systems, security alarms, weather monitoring stations, or agricultural automat
